Abstract:
Objective To explore the effect of sustained performance on EEG approximate entropy (ApEn).Methods Fifty participants were divided into two groups according to whether they had undergone sustained performance .One day af-ter the sustained-performance group finished executing their task , the resting EEG of nine electrodes ( F3, Fz, F4, C3, Cz, C4, P3, Pz and P4) was acquired in two grups separately , and the ApEn of each electrode was calculated as well . Results The ApEn of F3 and Fz showed an evident decrease as well as randomness of spontaneous brain electrode activity in frontal lobes , especially in the left one .Conclusion The drop of ApEn and the asymmetry of frontal lobes might reflect participants′state of fatigue during sustained performance .
