The informativeness of the high-frequency EEG for the assessment of the functional state of the brain has been proven by means of a new method of analysis of the EEG which is suitable, by contrast with the traditional spectral correlation analysis, for the description of nonlinear processes. Evidence has been obtained in favor of the hypothesis that a deterministic chaotic component, the parameters of which depend on the region of recording of the EEG and which changes conjointly with change in the functional state of the brain, is present in the EEG of the neocortex and hippocampus of the rabbit.
通过一种新的脑电图分析方法已证明高频脑电图对于评估大脑功能状态具有信息价值，与传统的频谱相关分析相比，该方法适用于描述非线性过程。已获得证据支持这样的假说：在兔的新皮层和海马体的脑电图中存在一个确定性混沌成分，其参数取决于脑电图的记录区域，并且随着大脑功能状态的变化而共同变化。
