Abstract

The spectral-correlation analysis of biopotentials in the cortex and some other brain structures (the anteroventral thalamic nucleus, dorsal hippocampus, lateral geniculate body, mid-brain reticular formation), in chronic experiments on alert rabbits, revealed that during electrical stimulation of thalamic mid-line nuclei within the ranges of 1-3, 4-7 and 8-10 c/s, there occured a rearrangement of the EEG frequencies; a dominant, narrow-band peak at the stimulation frequency, appeared. The coherence of the biopotentials of different cortical areas, of the cortex and subcortical formations increased during the stimulation at the frequency of the stimulation, reaching maximum values between the potentials of the visual and sensorimotor cortical areas.

摘要

在对清醒家兔进行的慢性实验中,对皮层及其他一些脑结构(丘脑前腹核、背侧海马、外侧膝状体、中脑网状结构)中的生物电位进行频谱相关分析发现,在1 - 3、4 - 7和8 - 10赫兹范围内电刺激丘脑中线核时,脑电图频率发生了重新排列;在刺激频率处出现了一个占主导地位的窄带峰值。在以刺激频率进行刺激时,不同皮层区域、皮层与皮层下结构的生物电位之间的相干性增加,在视觉皮层和感觉运动皮层区域的电位之间达到最大值。
