Abstract

Spike discharges of single neurons in the forebrain general cortex of the turtle were recorded extracellularly during habituation to light flashesmthe amplitude of spontaneous spikes, short-latent evoked spikes and spikes after the inhibitory pause was measuredmthe amplitude of short-latent evoked spikes significantly decreased during habtiuation while the background and postinhibitory spikes remained unchanged. It is supposed that the pattern of synapses activated by a definite stimulus may change the state of the elcetrically excitable neuronal membrane during habituation

摘要

在乌龟前脑一般皮层中，对单个神经元的锋电位进行了细胞外记录，记录过程是在对闪光的习惯化过程中进行的；测量了自发放电锋电位、短潜伏期诱发电位和抑制性暂停后的锋电位的幅度；在习惯化过程中，短潜伏期诱发电位的幅度显著降低，而背景和抑制后锋电位保持不变。据推测，在习惯化过程中，由特定刺激激活的突触模式可能会改变电兴奋性神经元膜的状态。
