Abstract

Trace unit activity in the visual and sensorimotor cortical areas was studied in alert rabbits after photic and electro-cutaneous stimulation. The ability of the sensorimotor area to preserve temporal stimulation pattern in the afteraction interval was higher than that of the visual area. Maximal rhythm preservation and a higher level of distant correlation in cortical unit activity were seen after synchronous bimodal stimulation. The data obtained suggest some diversity of the mechanisms of trace and evoked activity of cortical neurones.

摘要

在对警觉的兔子进行光刺激和皮肤电刺激后，研究了视觉和感觉运动皮层区域的痕迹单位活动。感觉运动区域在后续作用间隔中保持时间刺激模式的能力高于视觉区域。在同步双峰刺激后，皮层单位活动中出现了最大节律保持和更高水平的远距离相关性。所获得的数据表明皮层神经元的痕迹活动和诱发活动机制存在一定差异。
