摘要：
The electroencephalogram is not stochastic but deterministic chaotic. We study the underlying dynamics of emotional states in the human brain by a nonlinear dynamical analysis. We use the T3 and T4 channel among the 21 channels, measured upon auditory stimuli well, in the EEG. The purpose of this research is to estimate the bispectrum for the EEG in positive acid negative emotional states evoked by the auditory stimuli. As a result, we found the fact that in positive emotional state the degree of interaction of similar frequency pair is high, but in negative emotional state the degree of interaction of different frequency pair is high.
