The research on eeg coherence around central area of left hemisphere according to grab movement of right hand

Abstract

This study is to find significant EEG coherence for predict movement. Eight students were asked to visuo-motor task and their EMG at flexor carpi radialis of right hand and EEG at C3 and 4 orthogonal points 2.5 cm away from C3 were measured. EEG coherence between non-motor area and motor area and between motor areas were analyzed based on movement duration calculated from EMG activation, movement delay and coherence delay. In the results, most participants showed significant coherence between sensory or frontal and motor area discriminating movement and non-movement. However, there were individual differences in areas and frequency band showing significant coherence. © 2009 Springer Berlin Heidelberg.
