Abstract

Activity of single units in the visual and sensomotor cortex of an uncurarized, unanesthetized rabbit was recorded by means of two independent microelectrodes during photic stimulation at different frequencies. Trace effects characterized by repetition of the temporal structure of afferent stimulation and by an increase in the level of intercellular correlation were discovered mainly on analysis of distant interneuronal relations after stimulation with frequencies of 2 and Hz. Stimulation at a frequency of 8 Hz did not evoke trace effects.

摘要

在未使用箭毒、未麻醉的兔子的视觉和感觉运动皮层中,通过两个独立的微电极在不同频率的光刺激期间记录单个神经元的活动。主要在分析频率为2赫兹和赫兹的刺激后远距离神经元间关系时发现了以传入刺激的时间结构重复和细胞间相关性水平增加为特征的痕迹效应。8赫兹频率的刺激未引发痕迹效应。
