Abstract

Five pairs of chronic spinal rats were trained to lower a hind leg and then were tested for retention using a counter-balanced instrumental avoidance paradigm in which one animal served as the experimental and the other as a yoked control subject. An additional three pairs of rats were used in this paradigm after their lumbosacral spinal cords had been removed by aspiration. The results indicate that the chronic spinal rat is capable of instrumental avoidance conditioning when leg lowering is the response, and that the lumbosacral spinal cord is essential for this phenomenon.

摘要

对五对慢性脊髓大鼠进行训练，使其放下一条后腿，然后使用一种平衡的工具性回避范式进行记忆测试，在该范式中，一只动物作为实验组，另一只作为配对对照。另外三对大鼠在通过抽吸去除腰骶脊髓后，也用于该范式。结果表明，当放下腿部作为反应时，慢性脊髓大鼠能够进行工具性回避条件反射，并且腰骶脊髓对此现象至关重要。
