patients with PD compared with controls (10). These regions were PMC, M1, BA3, and BA1&2, which were defined with reference to the multimodal parcellation by Glasser et al. (33). Details are described in the Supplemental Method “Region-based source analysis.”. Therefore, in each of the six conditions, for each subject, we obtained between 8 and 13 ICA components for each of the four brain regions. Detailed information regarding the average number (means ± SD) of components of each region across patients/controls in each of the six conditions is provided in Supplemental Table S3.
