Fig. 3. Voxelwise results for linear regression of D₁ and D_2/3 dopamine receptor availability and total change in exit threshold.

Voxels that remain significant at a threshold of TFCE FWE corrected for multiple comparisons at a threshold of p < 0.05, two-sided, small volume corrected within the basal ganglia. Significant voxels for regression between total change in exit threshold and D₁-receptor availability (n = 45 individual participants) are colored red, D_2/3-receptor availability (n = 40 individual participants) are colored blue, and overlapping voxels significant for both D₁- and D_2/3-receptor availability are colored yellow.
