Here are three core contents of such framework:(1) cognitive process is reflected by the temporal, frequency, and spatial evolutions of EEG signals;(2) cognitive process is reflected by different nonlinear oscillations and transients of EEG signals;(3) cognitive process is reflected by the linear/nonlinear coupling and synchronization of EEG signals at different brain regions.

本文的一个理论创新在于首次提出认知动力学系统这一新概念，使得对认知功能的研究建立在一个理论框架下，其核心内容包括三方面：(1)认知过程通过EEG脑电活动在时间，频率，空间上的动态演化体现出来；(2)认知过程通过EEG脑电活动的非线性振动与各种刺激诱发的暂态体现出来；(3)认知过程通过EEG脑电活动在各脑区的相互耦合与同步谐振体现出来。
