Behavioral synchronization is shown not only between intra-species but also between inter-species. Previous studies reported that behavioral synchronization occurs between dogs and their owners by affiliative bonds and dogs' social skills for communicating with humans acquired by domestication. Horses also have such bonds and skills like dogs, however, there have been few empirical studies of behavioral synchronization between horses and humans. Therefore, we investigated whether the gait synchronization occurs between the horse and his/her familiar human participant while they were walking together by using angular statistics and how horses and umans interacted by analyzing entrainment. Only when human gait rhythm was controlled to be constant, gait synchronization between horse and human participants was found, though entrainment occurred only in humans. When horses and humans were walking in a more natural and uncontrolled situation, entrainment occurred in both horses and humans, though their walk adjustment did not reach synchronization. These results suggest that gait synchronization occurs between horses and humans and walk adjustment from humans is involved in such synchronization.

スナメリ (Neophocaena asiaeorintalis) は通常,比較的少数の群れをつくる.採餌行動においても一つの魚群に対して複数のスナメリが採餌を行うが,そこでは一部のイルカで見られるような明示的な役割分担は見られない.しかし,それぞれの個体が他個体を無視し,完全に単独で採餌しているかどうかは明らかではない.本研究ではドローンによるスナメリの採餌行動の動画を用い,スナメリの採餌行動に集団性が見られるかどうかを検討した.

<p>Heart rate variability (HRV) is a physical and noninvasive index of the autonomic nervous system and has been used in a wide range of fields such as human medicine, veterinary and animal behavior. Measuring devices have been improved miniaturization and light-weighting and they make it possible to measure a dog's electrocardiogram (ECG) under a free moving condition. HRV has been known as an index not only of physical activity but also to evaluate an animal's emotional status. One concern is a difficulty in dissociating physical activity and emotional status in HRV parameters. In this study, we examined how the physical activity component and the emotional component affect in HRV. We measured HRV and acceleration of the dogs under two conditions, the physical activity (motion) condition and the reward condition where food treats were emotional stimuli and under the motion condition. As a result, a dog's HRV values were linearly regressed on the acceleration data. SDNN (Standard Deviation of NN intervals) affected by the composite acceleration in reward condition while rMSSD (root Mean Square of Successive Differences) affected in motion condition. These suggested that the physical activity and HRV indices distribute on regression lines and emotional stimuli influences each HRV indices differently.</p>

局所脳冷却には,てんかん発作を抑制する効果があることが知られている.このことから,局所脳冷却の埋め込み型てんかん抑制装置への応用が期待されている.しかし,局所脳冷却がてんかん発作を抑制するメカニズムは未だ明らかになっていない.本研究では,温度依存的に反応速度が変化する Hodgkin-HuxIey 型イオンチャネルモデルを用いて新皮質の神経ネットワークのシミュレーションを構築し,冷却に伴うイオンチャネルの反応速度の低下がてんかん発作に与える影響を検討した.
