Abstract :
A non-parametric method for calculating the time evolution of coherence is reported. Interpretation of changes in coherence between EEG signals recorded from the left and right primary sensorimotor areas, and from the supplementary motor area and contralateral sensorimotor area, for right finger movements, are discussed
