Table I.
Spatial extent of the estimated dopamine release induced by the reward task, represented as the percentage of significant voxels exceeding the threshold of t > 5 within each activated region

BA11 = medial orbitofrontal cortex (mOFC); BA10 = ventromedial prefrontal cortex (vmPFC); BA32 = dorsal anterior cingulate cortex (dACC); L = left; R = right.
Right columns represent main results from the reward task, based on Δresponse bias (computed as RB (block 6) – RB (block 1)) and the probability of a rich miss immediately after a rewarded correct identification of the rich stimulus.
