Abstract

Hippocampal unit responses to conditioned stimuli were analyzed in intact rats and in rats deprived of the input from the entorhinal cortex to the hippocampus. Cells in normal rats responded more intensely to a conditioned stimulus when it was applied within 1 min from a previous one. The rats with lesions had smaller conditioned hippocampal responses and, in addition, there were no differences between responses to stimuli applied after short or long intertrial intervals. No effects on gross conditioned behavior were noticed.

摘要

在完整大鼠以及被剥夺从内嗅皮层到海马体输入的大鼠中，分析了海马体对条件刺激的单位反应。正常大鼠中的细胞，当一个条件刺激在距前一个条件刺激1分钟内施加时，对其反应更为强烈。有损伤的大鼠海马体的条件反应较小，此外，对短或长的试验间隔后施加的刺激的反应之间没有差异。未观察到对总体条件行为的影响。
