…In the late 1950s, a new method was used to record neuronal activity from unanesthetized animals. HH Jasper and his colleagues seated an unanesthetized monkey in a chair with a collar, and used a manipulator attached to its head to record neuronal activity from the cerebral cortex. They then used light as a conditioned stimulus, and formed a conditioned reflex in which the forearm was bent by an electric shock to the skin of the forearm as an unconditioned reflex, and recorded the neuronal activity of the cerebral cortex during this process (1958). It was found that the number of neuronal discharges in the cerebral motor cortex increased or decreased during this conditioned escape reflex. … *Some of the terminology explanations that mention "Jasper, HH" are listed below.

…1950年代の後半には,新しい方法として,無麻酔で行動している動物からニューロン活動を記録する方法が用いられるようになった。ジャスパーH.H.Jasperらは,無麻酔サルを首かせのついた椅子に座らせ,あらかじめ頭に固定したマニピュレーターで大脳皮質からニューロン活動を記録できるようにしたうえで,光を条件刺激とし,前腕の皮膚の電気ショックによる前腕の屈曲を無条件反射として条件反射を形成し,その過程での大脳のニューロン活動を記録した(1958)。この逃避条件反射時に,大脳運動野のニューロンの放電数は増加もしくは減少することが見いだされた。… ※「Jasper,H.H.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
