Fig. 3: Interaction effects of Group × methylphenidate (MP) Challenge between cocaine use disorder (CUD) and healthy controls (HC).
From: Expectation effects on brain dopamine responses to methylphenidate in cocaine use disorder
CUD has blunted responses to MP in putamen, caudate, and nucleus accumbens as compared to HC. The SPM images were superimposed onto T2-weighted magnetic resonance images in coronal (left upper) and sagittal (right upper) views. The color bar indicates t score values. Red represents the highest value and dark violet represents the lowest value. The bar chart showed DA release (PL–MP) in striatal regions in CUD and HC
