Abstract

Linear and non-linear phase relationships between EEG signals, measurement different electrode positions were analysed. Using second and third order statistics relations between cortical areas during preparation and execution of finger movements were investigated. Interrelations between left and right primary hand areas and between left hand area and supplementary motor area were computed. For linear analysis coherence and for non-linear interrelations crossbicoherence was used. Intrasignal relations were quantified with the bicoherence
