Maps and mean neural activity for respective clusters of dipoles.

A. Top: Mapping of the F-values for the interaction CONDITION and HEMISPHERE on a cortical surface for average time intervals, for both spoken and sung modalities. Bottom: Mean neural activity for the respective clusters of dipoles for all conditions and for both spoken and sung modalities. Error bars denote one standard deviation. B. Top: Mapping of the F-values for the main effect group on a cortical surface for average time intervals, for both spoken and sung modalities. Bottom: Mean neural activity for the respective clusters of dipoles for both groups and for both spoken and sung modalities. Error bars denote one standard deviation.
