摘要：In the present study, twelve volunteers were participated in a 2 h continuous mental arithmetic task without any break, which was designed to induce mental fatigue. The negative influence was investigated through EEG coherence, which was used as a measure of synchronization of different underlying brain regions. It was observed that the sustained mental task led to increased EEG coherence, which did not result in more efficient performance. The change of EEG coherence was widespread not limited to specific brain regions or frequency bands. The variation of EEG coherence combined with behavior performance validated the impact of mental fatigue caused by a continuous mental task. ? Springer-Verlag Berlin Heidelberg 2014.
