Selected local maxima and minima of activations and deactivations during interactive improvisation.

Coordinates described according to the Montreal Neurological Institute system were obtained from a random effects analysis of contrasts of [ Improv > Control ] masked inclusively with [ Improv > Rest ] and [ Control < Improv ] masked inclusively with [ Rest < Improv ]. Threshold was for contrasts and for masks.
