There are many studies on a variety of social behavior mediated by oxytocin. Of the studies, several suggest that oxytocin is deeply involved in empathy. Empathy toward other individuals is thought to be necessary to give rise to helping behavior. However, there has been little research on the relationship between oxytocin and helping behavior. We investigated helping behavior in oxytocin receptor knockout prairie voles. Prairie voles are known as socially monogamous rodents with high sociality. To examine helping behavior, we used a paradigm in which voles helped a conspecific soaked in water by opening a door. The prairie voles were housed in pairs. All the pairs were siblings. One of the pairs was assigned to be a soaker vole and the other was assigned to be a helper vole. There were two groups; the oxytocin receptor knockout and wildtype groups. The oxytocin receptor knockout voles were paired with wildtype siblings and were assigned to be the helper. Their wildtype cagemates were assigned to be the soaker. The experimental apparatus was divided into two areas; a pool area and a ground area. These areas were separated by a transparent acrylic plate on which a circular door was attached. The soaker vole was placed in the pool area and the helper vole was placed in the ground area. The door could be opened only from the ground area. We measured door-opening latencies. After the door-opening, the pair of the voles were allowed to interact. At that time, the huddling time was measured. As a result, the oxytocin receptor knockout voles showed significantly longer latencies for opening the door than the wildtype voles. In addition, the oxytocin receptor knockout voles showed shorter huddling time than the wildtype voles. These suggest that oxytocin is important for empathic behavior.

Episodic memory is defined as a memory system that consciously carries out recollecting one's subjective past experience and re-experiencing it. Through these mental activities, episodic memory is thought to make mental time travel retrospectively and prospectively possible, which is sometimes considered to be unique to humans. However, after a seminal study in scrub-jays by Clayton & Dickinson (1998), animal models of episodic memory have been developing and are starting to affect the concept of human episodic memory itself. This paper will concentrate on reviewing the studies that could encourage nonhuman animals to utilize memory — the properties are consistent with current definition of human episodic memory. Additionally, a discussion on the possibility to divide the system of episodic memory into two sub-processes and to study in animals the sub-processes of episodic memory will be undertaken.

ニホンザル1頭を対象にエピソード記憶を要する課題を学習させた。3面モニター内にバーチャル迷路を作り出し,その迷路内を,ジョイスティックを用いて自由に移動し,目標物体を見つけ出す課題の訓練をおこなった。サルはそのエピソードを覚え,続く試行ではより早く目標に到達することができるようになった。また,ラットを対象に,8方向の放射状迷路を用いた「いつ」「どこ」「なに」というエピソード記憶を必要とする課題を学習させた。今後,損傷実験やニューロン活動の記録実験を通して,エピソード記憶の神経機構について検討する予定である。
