The purpose of this study was to reveal the relation between the characteristics of emotional contagion and the mirror system activity. Thirty-one university students participated in this experiment. Emotional vocalizations and video of hand reaching and grasping a cup were presented to the participants. Facial electromyography (EMG) as emotional contagion index was recorded while presenting emotional vocalizations. Mu rhythm desynchronization in electroencephalogram (EEG) as mirror system activity index was recorded while presenting the video. The result shows significant correlation between the activity of facial EMG and desynchronization of mu rhythm, suggesting a person who is likely to be affected with emotional vocalizations also shows high mirror activity.

人類の寒冷適応や病気との関係が示唆されているミトコンドリアDNA多型(ハプログループ)を遺伝的背景の一つとし、ヒトの生理的多型を構成する遺伝要因を明らかにすることを目的とした。研究は主に寒冷曝露時及び低圧低酸素時のヒトの生理反応を検討した。10℃及び16℃の寒冷曝露実験では、ハプログループDが耐寒性に優れた。また4000m相当の低圧低酸素環境に曝露した時、Dグループは他のグループより血中酸素飽和度が高かった。以上よりミトコンドリアDNA多型はヒトの生理反応に影響し、生理的多型の一部を説明する可能性を示した。
