AB - This paper investigates the influence of alcohol on brain complexity. Considering electroencephalogram
(EEG) has the nonlinear dynamics characteristic of time-varying and non-stationary, we introduced
the Wavelet Entropy (WE) analysis. We denoise EEG signal by using wavelet decomposition, then
calculated the wavelet entropy of the denoised signal and analyzed the nonlinear complexity of the
signal. The results shows that the EEG wavelet entropy of drinkers' is markedly greater than the EEG
wavelet entropy of normal people's. The EEG complexity of drinkers' is higher and the brain of drinkers'
is in a more chaotic state. In the case of three kinds of external stimulus, we can get the change rule
of the normal people's and alcoholics' EEG, and then analyze the WE and the effects of alcohol on the
brain through a long duration of time. The long-time excessive drinking causes damages to the nerve
cells, which means the human brain consciousness becomes poor, and response is slow.
