Fig. 3.

Mean relative power for each region of interest (ROI) in unimodal Hall+ (left) and Hall- (right) patients displayed as a color-coded map on a parcellated template brain viewed from, in clockwise order, the left, top, right, right-midline and left-midline. Panel A: relative power in the theta band. Panel B: relative power in the beta band. Panel C: relative power in the gamma band. Panel D: Peak frequency. Hot and cold colors indicate higher and lower relative power/peak frequency, respectively. See table S1-S4 for the subcortical regions per frequency band that showed significant difference between the groups and for all the relative power and peak frequency values in the two groups.

Hall-: Parkinson's disease patients without hallucinations; unimodal Hall+: Parkinson's disease patients with only visual hallucinations.
