Abstract

Autospectral characteristics (ASC) of potentials of different neocortical areas of dogs in a state of quiet wakefulness were studied in a wide frequency band (1-100 Hz) by means of correlation-spectral analysis. A transition from evaluation of the mean power tendencies to a construction of distributions of different power levels for each of five arbitrarily chosen frequency bands permitted to reveal regional differences in ASC of each animal as well as interindividual EEG distinctions. The regional differences observed in all frequency bands (though not equally expressed) including the higher ones indicate not only the informativity of high-frequency components of electrical neocortical activity but also their neuronal origin.

摘要

通过相关谱分析，在宽频带（1 - 100 Hz）下研究了处于安静觉醒状态的犬不同新皮层区域电位的自谱特征（ASC）。从评估平均功率趋势转变为构建五个任意选择的频带中每个频带不同功率水平的分布，这使得能够揭示每只动物ASC的区域差异以及个体间脑电图的差异。在所有频带（尽管表达程度不同）包括高频频带中观察到的区域差异不仅表明了新皮层电活动高频成分的信息性，还表明了它们的神经元起源。
