However, the CCA method only chooses the frequency in the reference mode that corresponds to the maximum correlation value as the target. This may make the CCA output less robust. In this study, we propose a one-class support vector machine based filter to filter the sequences of correlation values in the process of the detection of SSVEP signals. The results demonstrate that the classification accuracy improved over different time windows for all subjects and the improvement achieved approximately 10% for some subjects. Moreover, the ratio of instructions that were filtered incorrectly was relative low (less than 5%) if the SSVEP signals were generated effectively..

This behavior is called action understanding, and it has an important influence on mental development, language comprehension, and socialization. In this study, we used functional near-infrared spectroscopy (fNIRS) to obtain brain signals related to action understanding and then classified different intentions. Aiming to overcome the drawbacks of traditional multiclass classification methods of one-versus-rest (OVR) and one-versus-one (OVO), in this paper, we propose a new effective method to solve multiclass classification that is a combination of OVR and OVO. Compared with OVO, this new method effectively improved the accuracy of four-class classification from 25% to 48%..

Chayapol Chaiyanan; Keiji Iramina; Thanate Angsuwatanakul; Boonserm Kaewkamnerdpong, Response time analysis on implicit learning induced by cognitive tasks toward developing ADHD treatment, Biomedical Engineering International Conference (BMEiCON), 2017.09, Attention Deficit Hyperactivity Disorder is a neurological disorder that affects many children in the world. Many scientists have speculated that behavior therapy is an essential part of treatment for people with ADHD. One of the promising behavioral therapy is neurofeedback therapy. Using neurofeedback, therapist can learn how to modulate patients' brain activity by adjusting the training regimen. Identifying when a patient achieve implicit learning event can potentially help in designing the neurofeedback treatment to help people with ADHD. According to past research, it was speculated that implicit learning and children with ADHD could have an atypical relationship. The aim of this paper to analyze response times of healthy people while they perform cognitive tasks to differentiate between people who has gained implicit knowledge and those who did not. The data showed that there is a clear distinction between people who had gained implicit knowledge and those that did not..

Ruimin Wang, Risako Kamezawa, Aiko Watanabe, Keiji Iramina, EEG alpha power change during working memory encoding in adults with different memory performance levels, Engineering in Medicine and Biology Society (EMBC), 2017 39th Annual International Conference of the IEEE, 2017.07, Working memory (WM) capacity affects our daily life in many ways, and its decrease often associates with neural disorders (e.g. Alzheimer's disease). Several studies have confirmed that alpha rhythms play an active role in memory mechanism. In the present study, we designed a digit verbal span experiment to find out that how the alpha power change during working memory encoding, and the relationship between alpha power and individual WM performance. Consistent with previous studies, our results confirm that alpha power is positively related to WM performance. Participants who had higher alpha power during WM encoding achieved better memory performance. We can conclude that the reason is alpha rhythms reflect inhibition of task-irrelevant information. Howbeit, a linear relationship between WM load and alpha power amplitude during memory encoding cannot be deduced in our experiment..

In this study, we aimed to provide additional scientific evidence with more insight on how the brain functions at a good/bad cognitive state than the usual statistical analysis. We introduced the brain activation measurement using baseline-normalized ERSP to determine the activation of EEG data from stimuli. These active points over a period of time could reflect brain synchronization due to stimuli. We also demonstrated the use of proposed measure on attention working memory data. The results indicate the potential of using the proposed measurement in categorizing the brain cognitive state and identifying some important factors to provide additional evidence to the field in the future..

We previously developed a robotic hand rehabilitation system triggered by multichannel near-infrared spectroscopy (NIRS) to address this demand. In a preliminary prototype system, a robotic hand orthosis, providing one degree-of-freedom motion for a hand's closing and opening, is triggered by a wireless command from a NIRS system, capturing a subject's motor cortex activation. To examine the feasibility of the prototype, we conducted a preliminary test involving six neurologically intact participants. The test comprised a series of evaluations for two aspects of neurorehabilitation training in a real-time manner: classification accuracy and execution time. The effects of classification-related factors, namely the algorithm, signal type, and number of NIRS channels, were investigated. In the comparison of algorithms, linear discrimination analysis performed better than the support vector machine in terms of both accuracy and training time. The oxyhemoglobin versus deoxyhemoglobin comparison revealed that the two concentrations almost equally contribute to the hand motion estimation. The relationship between the number of NIRS channels and accuracy indicated that a certain number of channels are needed and suggested a need for a method of selecting informative channels. The computation time of 5.84 ms was acceptable for our purpose. Overall, the preliminary prototype showed sufficient feasibility for further development and clinical testing with stroke patients..

32. Keiji Iramina, Measurement and Control of Human Brain Dynamics, ICSE2016, 2016.12, This study focuses on measuring and controlling of human brain dynamics using noninvasive techniques. I will give two topics in this study. One is a transcranial magnetic stimulation (TMS) which is possible to control of neuronal excitability. We applied TMS to cognitive studies for visual perceptions. The other one is a non-restraint cognitive monitoring system and its’ application to a child with mental deficiency. The objective our system is toward gaining information about the actual user state, including intentions, situational interpretations and emotions..
33. Keiji Iramina, Evaluation of soft neurological signs in children with developmental disorder and elderly people by measurement of pronation and supination, BMEiCON2016, 2016.12, Pronation and supination is the one of the soft neurological signs which shows the abnormality in children with developmental disorders such as ADHD or autistic syndrome. We developed a portable system to evaluate pronosupination by wireless acceleration and angular velocity sensors. In order to evaluate the difference between typically developing children and children with ADHD, we measured pronation and supination of typically developing children and children with ADHD. Accuracy, cooperativeness and stability were investigated to analyze the pronation and supination. We obtained the reference curve of the neuromotor development of children. Our results suggested that the pronation and supination function in children with ADHD has a tendency to lag behind that of typically developing children by several years. We also investigated the feature of elderly people. From these results, our system has a possibility to objectively evaluate the neurodevelopmental delay of children with ADHD and neuromotor dysfunction of elderly people..
34. Aya Sato, Xiangqun Liu, Tesuya Torii, Masakuni Iwahashi, Keiji Iramina, Modulation of Motor Cortex Excitability by Peripheral Magnetic Stimulation of Different Stimulus Sites and Frequencies, 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Soceity, 2016.08, Peripheral stimulation is known to influence the state of cortical excitability. The purpose of this study is to investigate whether peripheral magnetic stimulation has similar effects on cortical excitability to transcranial magnetic stimulation (TMS). A magnetic stimulator with a flat figure-of-eight coil was used for both TMS, and peripheral magnetic stimulation applied to the bilateral forearms. TMS was performed on the left primary motor cortex to evaluate influence of the peripheral magnetic stimulation, and motor evoked potential (MEP) was measured from the right first dorsal interosseous. Peripheral magnetic stimulation was performed at a stimulus frequency of 1 Hz or 10 Hz, to the stimulus sites on the right and left supination of the forearm. The effects of peripheral magnetic stimulation were evaluated by comparing the mean MEP amplitude elicited by TMS before and after peripheral magnetic stimulation. We found that cortical excitability varied according to the stimulation site and frequency of the peripheral magnetic stimulation. The inhibition of cortical excitability was observed following 1 Hz peripheral magnetic stimulation over the right forearm (p<0.001). In contrast, increased cortical excitability was observed using 1 Hz peripheral magnetic stimulation over the left forearm and 10 Hz stimulation over either the right or left forearms. We suggest that peripheral magnetic stimulation has a similar effect to TMS, and can induce both facilitation and inhibition of cortical excitability..
35. Ruimin Wang, Keiji Iramina, Sheng Ge, An Improved Multiple LASSO Model for Steady-State Visual Evoked Potential Detection, The 6th International Conference on the Development of Biomedical Engineering, 2016.06, Improving the classification accuracy in brain–computer interface (BCI) with a short data length is important to increase the BCI system’s information transfer rate. Least absolute shrinkage and selection operator (LASSO) has been examined to be an effective way to detect the steady-state visual evoked potential (SSVEP) signals with a short time window. In this paper, an improved multiple LASSO model for SSVEP detection is proposed, which can process multichannel electroencephalogram (EEG) signals without electrode selection. EEG data from twelve healthy volunteers were used to test the improvedmultiple LASSO model. Compared with the traditional LASSO model, the improved multiple LASSO model gives a significantly better performance with multichannel EEG data..
36. Takehito Hayami, Keiji Iramina, Xian Chen, Computer Simulation of Nerve Conduction Study of a Sural Nerve to Evaluate Human Peripheral Nervous System, The 6th International Conference on the Development of Biomedical Engineering, 2016.06, Nerve conduction study is a test to examine the function of electric signal transmission at the trunk of a peripheral nerve, which is an effective method for the diagnosis of diabetes to quantify the peripheral numbness and to evaluate the stage of this complication. In a routine test, the feature to measure in the electric potential waveform observed in this test is limited to the velocity and the amplitude of the peaks. To make the measurement more precise, the production process of the electric potential waveform should be observed carefully. In this study, nerve conduction study of a sural nerve, which is the most popular for the patients with diabetes, was simulated in a computer using general cable equation and neuroanatomical data. As a result, the approximate electric
potential waveform was reproduced, whereas the conduction velocity of the peaks was not completely conformed to the physiological data..

Kurniawan Eka Permana, Tsuyoshi Okamoto, Keiji Iramina, Single Channel Electroencephalogram Measurement with Multi Scale Entropy Analysis for Evaluating Day Time Sleep, The 6th International Conference on the Development of Biomedical Engineering, 2016.06, Nerve conduction study is a test to examine the function of electric signal transmission at the trunk of a peripheral nerve, which is an effective method for the diagnosis of diabetes to quantify the peripheral numbness and to evaluate the stage of this complication.

38. Aya Sato, Xiangqum Liu, Masakuni Iwahashi, Keiji Iramina, Alteration of the Motor Cortex Excitability by Modulation of the Stimulus Parameter of Peripheral Stimulation, The 6th International Conference on the Development of Biomedical Engineering, 2016.06, Transcranial magnetic stimulation (TMS) is known to elicit a conditioning effect on cortical excitability. The purpose of this study was to investigate changes in cortical excitability induced by peripheral stimulation with differing frequency and stimulation site. A magnetic stimulator with a flat figure-eight coil was used for TMS and was performed on the left primary motor cortex. The electrical stimulation and magnetic stimulation were used in peripheral stimulation and the stimulus sites were the right and left supination of the forearm. Peripheral stimulation was performed at a stimulus frequency of 1 Hz or 10 Hz. Alterations of cortical excitability induced by peripheral stimulation were evaluated by comparing the mean of the motor evoked potential amplitude elicited by TMS each before and after peripheral stimulation. We found that cortical excitability varied according to the stimulation site and frequency in both the electrical and magnetic stimulation over the forearm. The inhibition of cortical excitability
was observed in both 1 Hz electrical and magnetic stimulation over the right forearm. In contrast, the facilitation of cortical excitability was observed at 1 Hz electrical and magnetic stimulation over the left forearm, and it was confirmed for both the right and left forearms at 10 Hz electrical and magnetic stimulation. Moreover, regarding the alteration of cortical excitability induced by peripheral stimulation, it was confirmed that magnetic stimulation has more the significant difference than electrical stimulation. We suggest that peripheral stimulation by electrical and magnetic stimulation have a similar effect to TMS, and can induce both facilitation and inhibition of cortical excitability. Moreover, in the case of peripheral stimulation of the same stimulus frequency, we expect that the magnetic stimulation has more the significant effect than electrical stimulation to cortical excitability..
39. Keiji Iramina, Simultaneous Measurement of NIRS and EEG, 8th Chula Neurology Forum 2016, 2016.03, Near infrared Spectroscopy(NIRS) is a measurement of hemodynamic activity of the brain. On the other hand, EEG measures neuronal activity of the brain. Although both techniques can reveal the brain function, each measurement has several different charact.

, 8th Biomedical Engineering International Conference, 2015.11, This study proposed an alternative approach for analyzing visual working memory based on brain complexity to identify brain state condition for memorizing new scenes. Multi-scale entropy (MSE) was used for analyzing the complexity of Near Infrared Spectroscopy (NIRS) data which measured the hemodynamic response of brain during a cognitive experiment. The results revealed the distinctive entropy between remembered and forgotten cases in prefrontal area at FC3 position. The entropy of remembered case is higher than forgotten case; this could indicate that the brain requires more activity and then more hemodynamic responses for good memorizing. Hence, the results indicated the potential of using the complexity of NIRS for characterizing the brain state for working memory. .
45. Masaki Ono, Hiroki Furusyo, Keiji Iramina, Analysis of the complexity of EEG during the short-term memory task
, 8th Biomedical Engineering International Conference, 2015.11, By using fractal dimension and sample entropy, we investigated the complexity electroencephalogram (EEG) during an activity that uses working memory. We conduct a short-term memory test and a calculation task and analyzed 1.0s EEG data from 4 phases (resting, encoding, retrieval and calculation phase). As a result, fractal dimension analysis can reflect the activity ofthe working memory better than sample entropy analysis. Moreover, in order to investigate the relationship between the fractal dimension value and the power of theta band (4-8 Hz) in the frontal region, we conducted a correlation coefficient analysis. The result showed that increase of the power of theta band and decrease of fractal dimension value has relatively high correlation. In conclusion, the activity of working memory in frortal
part may be able to be captured by fractal dimension analysis..

, 8th Biomedical Engineering International Conference, 2015.11, The present study proposes the method of removing head movement artifact for considering real-time processing and improving reliability of EEG under unconstrained measurement. In the proposed method, independent component analysis and high-pass filtering were usefi with a hybrid accelerometer, which was used for detecting components containing head movement artifact. To evaluate the proposed method, we measured EEG which included the artifact and P300 components. As a result, although EEG amplitude decreased, original P300 waveform appeared clearly. This result indicates that the proposed method is effective for removing head movement artifact while keeping EEG information..
47. Yuya Onitsuka, Yoshiyuki Shiotsuka, Keiji Iramina, The difference in the kinds of stimulations in CIT based on ERP
, 8th Biomedical Engineering International Conference, 2015.11, The topic of our research is the detection of concealed information based on ERP (Event Related Potential). As a method to detect concealed information there is CIT (Concealed Information Test). CIT is used to detect intentionally concealed information, for example crime-related information, with subject’s physiological response to presented stimuli. We used visually CIT based on P300 in the experiment. There are three kinds of stimuli in CIT. One is ‘Probe’, which is related to concealed information. The other is ‘Irrelevant’, which is not related with it but consists of same category as Probe (ex; place, time and so on). And the other is ‘Target’, which is for calling subject’s attention to the experiment. In CIT, the subject’s reaction to those presented stimuli are measured and compared with each other
categories. If the reaction to Probe are different with one to Irrelevant the subject is considered as he knows Probe..

The use of tDCS is increasing in a variety of clinical fields as treatment for neuropsychiatric disease and neurological disorders. But it isn’t obvious how brain is affected by tDCS. In this study, we investigated the difference of current density distribution in brain by computational model. The aim is to estimate the difference of current density distribution in brain for position of tDCS electrodes. As a result, it turned out that the distance of two electrodes is one of important parameter.

, 7th Biomedical Engineering International Conference, 2014.11, Deep brain stimulation (DBS) is one of treatment for Parkinson’s Disease (PD). The diagnosis of Parkinson’s Disease is difficult because of its complexity.
Therefore, we have established an evaluation for the effect of treatment in DBS. We measure pronation and supination of forearms, which is used for diagnosis of PD, and analyze the motion of subjects by obtained acceleration and angular velocity. We use two indices for analysis. These indices by obtained results are useful for evaluation of treatment of DBS.

This research examines the prototype of early warning system for heart disease by android application. It aims to facilitate users to early detect heart disease which can be used independently. To build the application in android phone, variable centered intelligence rule system (VCIRS) as decision makers and pulse sensor - Arduino as heart rate detector were applied in this study. Moreover, in Arduino, the heart rate will become an input for symptoms in Android Application. The output of this system is the conclusion statement of users diagnosed with either coronary heart disease, hypertension heart disease, rheumatic heart disease or do not get any kind of heart disease. The result of diagnosis followed by analysis of the value of usage variable rate (VUR) rule usage rate (RUR) and node usage rate (NUR) that shows the value of the rule that will increase when the symptoms frequently appear. This application was compared with the medical analysis from 35 cases of heart disease and it showed concordance between diagnosis from android application and expert diagnosis of the doctors..

However, this index has a demerit in which evaluation results between doctors are not consistent. The present study aims to establish more quantitative and evaluating method. We have developed a simple and portable evaluation system to measure pronation and supination of forearms. In this study, we have measured the pronation and supination of the forearms of 261 subjects aged 7 to 12 years (healthy children : 201, ADHD children : 60) and compared the function of healthy children’s pronation and supination with the function of ADHD children’s pronation and supination by new indices. From the results, we could obtain a difference between healthy children and ADHD children. The results showed that our developed system has the potential to become diagnostic criteria for developmental disorders..

Though hearing one’s own name well has been studied, the relationship between hearing one’s own name and self-awareness is not understood. In this study, we focused on brain responses to hearing one’s own name. In order to assess the pattern of ERP and the power of EEG frequency during hearing one’s own name, we used a passive oddball paradigm that included the subject’s own name (SON). The grand average ERP showed that mismatch negativity and novelty p300 were elicited by SON. Time frequency analysis revealed that theta power and beta power were increased around 400-600 ms after stimulus by SON. .

electromagnetic induction of TMS coil in non-invasive and painless. However, it has not been known which location of
brain is stimulated because of the complicated structure of brain. In this study, we simulated the neuronal excitement
when TMS stimulated using finite-element method. At First, we made the brain sulcus model which consisted of CSF,
grey matter and white matter and made from cube elements size of 0.5mm. In order to improve the accuracy of the
calculation, cube elements size was set 0.5/3 mm only near the boundary surface in this study. Second, we applied TMS
stimulation to the model in some conditions. We were prepared 10mm, 20mm, 30mm, 40mm as the coil radius, and 0, 30,
45, 60 and 90 degree as the coil direction based the reference. Finally, we calculated the membrane potential and
compared to some conditions. As a result, we found that the membrane potential was rapidly changed at the white
matter-grey matter interface when the coil radius over 30mm and coil direction was within 45 degree from target area.
These obtained results give useful information about appropriate TMS parameters for the effective stimulation of the
target area in the brain..

The motion of pronation and supination of the forearm is used as a diagnosis method of developmental disability, etc. However, this diagnosis method has a demerit in which diagnosis results between doctors are not consistent. It is hoped that a more quantitative and simple evaluation method is established. Moreover it is hoped a diagnostic criteria obtained from healthy subjects can be established to diagnose developmental disorder patients. We developed a simple and portable evaluation system for pronation and supination of forearms. Three-dimensional wireless acceleration and angular velocity sensors are used for this system. In this study, pronation and supination of forearms of 570 subjects (subjects aged 6-12, 21-100) were examined. We could obtain aging curves in the neuromotor function of pronation and supination. These aging curves obtained by our developed system, has the potential to become diagnostic criteria for a developmental disability, etc..

Tetsuya Torii, Aya Sato, Masakuni Iwahashi, Yuji Itoh, Keiji Iramina, Time-Dependent Effects of Low-Frequency Repetitive Transcranial Magnetic Stimulation of the Supramarginal Gyrus, 34th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012.08, In this paper, we report our studies of the effects of stimulating the bilateral supramarginal gyrus (SMG) with
low-frequency transcranial magnetic stimulation (rTMS) or short-term rTMS on brain excitability in humans. We analyzed
the effects of various durations of stimulation on P300 latencies of the event-related potential (ERP). Magnetic pulses were
delivered using a figure-eight flat coil. The intensity of rTMS was set to 80 % of the subject’s motor threshold. In each round of rTMS, 100 magnetic pulses were applied over the scalp at frequencies of 1.00, 0.75, and 0.50 Hz. ERPs were measured prior to magnetic stimulation as a control. The effects of magnetic stimulation were then determined by measuring its effects on P300 latencies elicited by an odd-ball task. These latencies were measured before and 0, 5, 10, and 15 min after the magnetic stimulation. 1.00 Hz low-frequency rTMS of the left SMG decreased P300 latencies for approximately 10 min. In contrast, 0.50 Hz rTMS of the left SMG resulted in delayed P300 latencies for approximately 15 min. We furthermore found that 0.75 Hz rTMS of the left SMG and 1.00, 0.75 and 0.5 Hz rTMS of the right SMG did not affect P300 latencies. These results suggest that the duration of the effects of rTMS depend on the frequency of stimulation..

Tetsuya Torii, Aya Sato, Yukiko Nakahara, Masakuni Iwahashi, Keiji Iramina, Effects of Low-Frequency Repetitive TranscranialMagnetic Stimulation of the Supramarginal Gyrus on Event-related Potentials, 18th International Conference on Biomagnetism, 2012.08, The aim of this study was to investigate the effects of repetitive transcranial magnetic stimulation (rTMS) on brain activity. We investigated the effects of rTMS on P300 latencies as measured by electroencephalography (EEG) by stimulating the supramarginal gyrus (SMG), which is considered to be the area of origin of the P300. As the frequency-dependence of low-frequency rTMS has not been previously investigated in detail, we evaluated the effects of rTMS at frequencies of 1, 0.75, 0.5 or 0.25 Hz on P300 latencies. The odd-ball task was used to elicit P300s before and shortly after the scalp was stimulated by rTMS. Magnetic stimulation was performed over 100 pulses. The stimulus intensity was 80% of each subject’s motor threshold. EEG measurements were collected on the Fz, Cz and Pz line of the international ten-twenty system. At 1
Hz, P300 latencies after rTMS were shorter than P300 latencies before rTMS. The latencies were shortened by approximately 25 ms
at the Fz. At 0.5 Hz, P300 latencies were longer after rTMS. The latencies were lengthened by approximately 26 ms at the Fz. In contrast, at 0.75 or 0.25 Hz, no change in P300 latencies was observed after rTMS. Furthermore, following rTMS stimulation of the right SMG, there were no significant differences in P300 latencies compared with before the rTMS.
The results of this study show that changes in P300 latencies depend upon the frequency of rTMS when the left SMG is stimulated. However, there were no significant differences between pre- and post-rTMS regardless of the stimulation frequency when rTMS was applied to the right SMG. Thus, the results of this study demonstrate that rTMS over the right SMG is not frequency-dependent..

Kazuhisa Nojima, Dilok Puanhvan, Yoshinori Katayama, Yodchanan Wongsawat, Keiji Iramina, rTMS and tDCS to the motor cortex modulate event related desynchronization of mu wave, 18th International Conference on Biomagnetism, 2012.08, In our study, we studied the effects of repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) to the event related desynchronization (ERD). Muwave is traditionally defined as an 8-12Hz wave recorded over sensorimotor cortex. The power of mu wave decreases with imagination of movement. ERD describes the short lasting and regional localized amplitude attenuation or blocking of oscillations that occurs in direct relation to an event. Both rTMS and tDCS can modulate cortical excitability. The aim of this study is to investigate the rTMS and tDCS effects on the ERD of mu wave, when rTMS and tDCS induce the facilitation or inhibition of cortical excitability. EEGs were measured before and after stimulation. At one measurement, subjects were given 1Hz 600pulses 90%resting motor threshold (RMT) rTMS, 1Hz 600pulses 110% RMT rTMS, 1mA 10min anodal tDCS or 1mA 10min cathodal tDCS over the motor area of the thumb in the left hemisphere. The reference electrode of tDCS was fixed at the forehead of the right hemisphere. During the measurement of EEG, subjects were required to either relax, or image grasping the right hand, or actually grasp the right hand for 4seconds during every 4seconds interval as indicated by the word cues ’Relax’, ’Imagery’ or ’Movement’, which were displayed on the monitor. Each task was repeated ten times at one measurement. To investigate the differences between the effects of real stimuli and noise, sham rTMS and sham tDCS conditions were added in this experiment. We
analyzed the amount of difference ERD according to imagery or according to movement between before the stimulation and after the stimulation..

P300 latency of event-related potentials (ERP) was used to evaluate the effect of slow-frequency rTMS by stimulating the supramarginal gyrus (SMG). The frequency-dependence of slow-frequency rTMS isn’t investigated in detail. Therefore, we evaluated the effect of rTMS at frequencies of 1Hz or less on P300 latency. A total of 100 magnetic pulses were applied for rTMS. The odd-ball task was executed to set the control condition before rTMS. Next, the scalp was stimulated by rTMS. Finally, the odd-ball task was executed once again promptly after rTMS. With 1.00Hz rTMS to left-SMG, P300 latency shortened. In contrast, with 0.50Hz rTMS to left-SMG, P300 latency delayed. However, with 0.75Hz rTMS to left-SMG, P300 latency was unaltered. Results demonstrated that rTMS over the left-SMG has frequency-dependent effects and rTMS over the right-SMG is not frequency-dependent..

160. Tesuya Torii, Aya Sato, Masakuni Iwahashi, Keiji Iramina, Transition of After Effect on P300 by Short-Term rTMS to Prefrontal Cortex, IEEE International Magnetic Conference, 2012.05, In the present study, we analyzed the effects of repetitive transcranial magnetic stimulation (rTMS) on brain activity. The latency of the P300 component of the event-related potential (ERP) was used to evaluate the effects of low-frequency rTMS following stimulation of the dorsolateral prefrontal cortex (DLPFC), which is an area considered to be related to the generation of the P300. In addition, prolonged stimulation effects on the P300 latency were analyzed after applying rTMS. A figure-eight coil was used to stimulate the left or right DLPFC, and the intensity of magnetic stimulation was 80% of the motor threshold. A total of 100 magnetic pulses were applied for the rTMS. The effects of stimulation at frequencies of 0.5 or 1 Hz were determined. An odd-ball task was performed before and 5, 10, and 15 minutes after rTMS to measure the effects of rTMS on the P300. Electroencephalography (EEG) was measured at the Fz, Cz and Pz electrodes using the international 10–20 electrode system. We found that 0.5 and 1 Hz rTMS produced different effects on P300 latencies. 1 Hz stimulation of the left DLPFC lengthened P300 latencies by approximately 20 ms at the Cz, which lasted up to 15 minutes post-rTMS. In contrast, 0.5 Hz rTMS stimulation of the left DLPFC and 0.5 and 1 Hz rTMS stimulation to right DLPFC had no significant effects on P300 latencies. These results demonstrate that the effects of rTMS on the P300 latency depend on the frequency of
stimulant and the area stimulated. Furthermore, we have determined the duration of this effect of low-frequency and short-term rTMS..

Tetsuya Torii, Aya Sato, Yukiko Nakahara, Masakuni Iwahashi, Keiji Iramina, EFFECT OF THE SHORT-TERM MAGNETIC STIMULATION BY RTMS ON P300 LATENCY, The 4th Biomedical Enginnering International Conference, 2012.01, The purpose of this study is to investigate the effect of P300 latency in case of magnetic stimulation to human brain by rTMS (Repetitive Transcranial Magnetic Stimulation). The stimulation of rTMS is 100 pulses with 1Hz or 0.5Hz low fre-quency. The magnetic stimulation points are left-right SMG (Supramarginal Gyrus) and left-right DLPFC (Dorsolateral Prefrontal Cortex). In case of 1Hz magnetic stimulation to the left SMG, P300 latency after the magnetic stimulation was shorter than P300 latency before the magnetic stimulation. In case of 1Hz low frequency magnetic stimulation to the left DLPFC, P300 latency after the magnetic stimulation was later than before the magnetic stimulation. In case of 0.5 Hz low frequency magnetic stimulation to left SMG, the delay of P300 latency was observed. Generally, in the low-frequency magnetic stimulation equal to or less than 1Hz, the brain activity is inhibited by stimulating the brain. The activity of left SMG is excited at 1Hz and inhibited at 0.5Hz. As this reason, at first, in this study, the frequency of the magnetic stimulation is just 1Hz and this frequency is border of a low frequency and a high-frequency. Secondarily, the sensitivity for the magnetic stimulation varies by parts of brain. Therefore, this study suggests that the left SMG is activated by the short-term magnetic stimulation using rTMS (1Hz, 100 pulses). .

We could obtain reference curves of the neuromotor development for elementary school children using this system. The purpose of this system is screening the developmental disorder. We measured the pronosupination of five children suspected of having ADHD (children aged 7-12). We examined the difference of neuromotor development between normally developed children and children suspected of having ADHD. Measured results show children suspected of having ADHD have low performance compared with normally developed child. .

Takehiro Ikuno, Yoshinori Katayama, Keiji Iramina, Selection and removal of artifacts in EEG based on independent components, The 4th Biomedical Enginnering International Conference, 2012.01, Electroencephalogram (EEG) is the recording of electrical activity along the scalp. EEG is very small signals of a few μV. Artifacts arising from living body often mingle with the EEG. A brain computer interface (BCI) is a communication between a human brain and an external device using EEG. The artifacts interfere with driving the BCI system. They may change the features of nervous activity or even be incorrectly used as the source of control in BCI systems. Recently, independent component analysis (ICA) has become one of the most prominent techniques for EEG. A typical method removes the artifacts after the offline training using the ICA. However, the method is not suitable for BCI systems such as online driving. So, we propose a method to eliminate artifacts (especially blink artifacts) from the body. This method does not require offline training and processes close to the real-time processing..

Pronation and supination of forearm is a way to evaluate minor nervous dysfunction. It is able to diagnose developmental disorder.

It is said that the condition under 1Hz rTMS induces the inhibition effect. On the other hand, the condition over 1Hz rTMS induces the facilitation effect. However the number of pulses of rTMS is also important factor. In this study, we focused on the number of pulses. We used the cognitive task of perceptual reversal and compared the rTMS effects of different condition under 1Hz which is the inhibition
condition. It has been known that the right superior parietal lobule (SPL) has a role in perceptual reversal. We applied rTMS over the SPL and measured the inter-reversal time (IRT) of perceptual reversal. The results showed that when 0.25Hz 60pulses, 0.5Hz 60pulses and 1Hz 60pulses of rTMS was applied over the right SPL, the IRT was significantly smaller. On the other hand, when 1Hz 240pulses of rTMS was applied over the right SPL, the IRT was significantly longer. When 0.25Hz 120pulses, 0.5Hz 120pulses and 1Hz 120pulses of rTMS was applied over the right SPL, there were no significant differences. Furthermore, to investigate the rTMS effects, when rTMS are applied over the motor area, we measured the motor evoked potential (MEP). The more pulses of rTMS was applied, the smaller the amplitude of MEP became. From these results, it was found that the IRT of perceptual reversal and the amplitude of MEP primarily affected by the number of pulses of rTMS. .

This motion was measured by wireless acceleration and angular velocity sensor. The aim of this system is evaluation of minor nervous dysfunction. It is for the screening of the developmental disorder child. In this study, in order to confirm the effectiveness of this system, the reference curve of the neuromotor development was experimentally obtained. We studied 212 participants (108 males, 104 females) aged 7 to 12 years
attending the kindergarten school. We could obtain the reference curve of the neuromotor development using this system. We alsoinvestigated the difference of neuromotor function between normally developed children and a ADHD child. There is a possibility that abnormality of the minor nervous dysfunction can be detected by using this system. .

Mingdi XU, Keiji Iramina, The influence of stimulus onset asynchrony on neuronal suppressive phenomenon in face processing: An event-related potential study, 33rd International Conference of the IEEE Engineering in medicine and Biology Society, 2011.09, It has been reported that if two sensory stimuli are presented consecutively with stimulus onset asynchrony (SOA) of as short as several hundreds of milliseconds, the neural activity, elicited by the second stimulus, in the stimulus-sensitive area will be inhibited, say, suppressive phenomenon. Using a paired-stimulus paradigm, in which two visual stimuli were successively presented, we investigated the influence of SOA (200ms, 400ms & 600ms) on suppressive phenomenon in face processing. Twelve subjects were asked to passively view randomly ordered paired stimuli and single stimuli, while their event-related potentials (ERPs) were recorded simultaneously. To evaluate the suppression, we compared the ERPs elicited by the second face stimulus of the paired stimuli with that elicited by the single face stimulus. It was found that, comparing with the ERPs elicited by single faces, in all three SOA conditions, the ERPs elicited by the second face stimulus of the intra-category trials (face_face trials) were more suppressed than those of the inter-category trials (blank_face and building_face trials) in both occipitotemporal and frontal regions. We surmised that these results might support a “domain specific” theory, which suggested that visual processing of faces and non-face objects involve separate and specialized networks in the ventro-lateral temporal cortex. Interestingly, for the face_face trials, as the SOA increased, the ERP suppression in the frontal region diminished gradually. Such phenomenon might be due to the lasting effect of semantic processing for the first face stimulus. .
