Between-group differences in left/more affected STN – sensorimotor cortex functional connectivity. The sensorimotor cortex is represented by the regions of the Human Motor Area Template (HMAT): primary motor cortex (M1), sensory cortex (S1), dorsal premotor cortex (PMd), ventral premotor cortex (PMv), supplementary motor area (SMA), and pre-supplementary motor area (Pre-SMA). Results are in MNI space, thresholded at P < 0.05 (corrected using 3dClustSim in AFNI) and presented on axial slices of the Collin 27 average brain. The color scale provides information about the strength of between-group differences (expressed as t-value). L = left, R = right.
