Correlation of trial by trial submovements and BOLD activity in basal ganglia. Significant positive correlations for submovements at the group level, corrected for multiple test comparisons (FDR p<0.05) are shown in red for the viscous trials and blue for the target trials. Significant differences where the correlation with submovements was stronger for viscous than target challenge task are shown in yellow. On the left is plotted the mean beta +/− SEM for the entire population corresponding to the magnitude of the parameter correlating submovement and BOLD for the left GPi/STN (MNI: −14, −18, −6) and right GPi (MNI: 20, −10, −8). Coronal sections are −30, −23, −16, −11, −4, 2, 9, 13, 20mm relative to anterior commissure.
