The alpha frequency band rhythm that appears in central area
(mu wave) is suppressed by observation of an action. Mu wave suppression has been used as an index of human mirror system, which reflects action recognition
and empathy to others behavior. In the present study, we examined the effects of a tangible user interface on an observer’s brain activity. The participants
were fifteen right-handed males. Three types of user interface for learning art objects (tangible interface, touch panel interface, and keyboard interface) were
used. A manipulator grasps a model porcelain object as an input device and moves it to the plate with a sensor in front of the screen. A 64-channel
electroencephalogram (EEG) was measured while the participants were observing a person manipulating the user interface. Significant mu wave suppression
was found in the tangible interface condition and it was localized in the left central area. These results suggest that the tangible user interface with object-directed
and goal-oriented hand actions can enhance activity of the mirror neuron system in the sensorimotor area in observers.. |

Lee Si, Higuchi S, Association between genetic polymorphism of melanopsin photoreceptor and sleep/wake timing, 国際人類学民族科学連合(IUAES), 2014.05, The human sleep/wake cycle is adjusted by circadian rhythms that adapt to a 24-hour light/dark cycle. The melanopsin photoreceptor in the retina plays an important role in circadian photoentrainment in the natural environment. However, artificial light at night has adverse effects on human sleep and circadian rhythm in modern society. We have already found that melanopsin gene polymorphism is associated with pupillary light response, but the association with sleep/wake timing has remained unclear. A total of 348 healthy Japanese university students participated in this study. The genotypes of rs1079610 (I394T) located in the coding region were analyzed. Bedtime, wake time and midpoint of sleep on weekdays of CC subjects were significantly later than those of TT and TC subjects. We have already found that pupilloconstriction in subjects with the C allele is highly responsive to light. The delayed sleep/wake timing of CC subjects might be a consequence of the high responsiveness to light at night since exposure to light at night induces phase delay. C allele frequency of I394T in the European population is larger than that in the Asian-Japanese and Sub-saharan African populations. High responsiveness to light may be an adaptive trait for a short photoperiod in European people living in high latitude areas. However, our results suggest that high responsiveness to light is a cause of delayed sleep timing in adolescents living under artificial light at night in modern society.. |
