Abstract

Electrical characteristics of snail command neurons were studied during and after defensive conditioning. Tapping on the shell was used as a conditioned stimulus. A light air blow into the lung cavity orifice (pneumostome) was used as an unconditioned stimulus. The conditioned defensive reflex is known to be retained for 40 days. We have shown earlier the decrease in membrane and threshold potentials of command neurons after defensive conditioning (Gainutdinov et al., 1996). In these experiments it has been found that the decreased level of membrane and threshold potentials are maintained during 40 days after defensive reflex conditioning.

摘要

在防御性条件反射期间及之后，对蜗牛的指令神经元的电特性进行了研究。轻敲外壳用作条件刺激。向肺腔开口（气门）轻轻吹气用作非条件刺激。已知条件防御反射可保留40天。我们之前已经表明，防御性条件反射后指令神经元的膜电位和阈值电位会降低（加努季诺夫等人，1996年）。在这些实验中发现，防御反射条件反射后40天内，膜电位和阈值电位的降低水平一直保持。
