Task-related BOLD responses in the striatum in the placebo session, based on whole brain analysis (for a complete list of the results of this whole brain analysis see Supplementary Table S1)

Regions	BA	PFWE-corrected at cluster level	Peak Coordinates x, y, z	Peak T-value	Cluster size
A. Feedback-related BOLD responses that correlate positively with the size of the RPE
Ventral striatum		0.000	−19, 4, −13	7.68	1380
			11, 10, −5	7.23
			−9, 8, −7	6.89
B. Feedback-related BOLD responses that correlate positively with the size of the salience of feedback (absolute value of the RPE)
No significant striatal cluster was found
C. Choice-related BOLD response that correlates positively with RPE history.
Ventral striatum		0.000	11, 6, −5	7.01	1838
			−7, 10, −5	6.77
			1, −4, 9	5.85
Regions	BA	PFWE-corrected at cluster level	Peak Coordinates x, y, z	Peak T-value	Cluster size
D. Regions in which MPH reduced the BOLD response during feedback (across feedback types)
Ventral striatum		0.000	−19, 6, −17	4.70	131
			−23, 12, 3	4.70
			−23, 16, −9	4.35
Ventral striatum		0.012	25, 12, −7	4.61	70
			21, 20, −11	3.43
			21, 10, −15	3.43

Effects of MPH on the BOLD response during feedback (across feedback types). Local maxima more than 8.0 mm apart are shown.
