Fig. 4.

Source level time-course of maximal beta power change. In (a) the maximum beta band power change (%) from baseline is plotted over the course of the task for each subject. Shading indicates standard error as assessed by bootstrapping (100 bootstraps over trials). Colour coded asterisks indicate when each subject deviate significantly from rest (p < .05, corrected). In (b) the location of these maximal beta band power changes (all left hemisphere) are indicated by the spheres imbedded in the surface render of the MNI template.
