Study on Brain Fatigue Based on EEG Signals

Abstract:

In order to detect human brain fatigue,we recorded EEG signals of 50 subjects by means of MP150 recorder system.The subjects were divided into two groups.One group was in mind fatigue state,the other was controled group who had full of energy.We analysed the EEG signals by wavelet packet decomposition method.After analysis and reconstructure operation,we got the α,β,γ,δ rhythm and the power spectrum distribution of these componengts.Compared with the control,the human in fatigue state have enhanced α wave and reduced β wave.So the conclusion is that the redistribution of α and β wave could regard as a potential diagnostic critera of brain fatigue.
