Prediction error-related activity during acquisition. (A) Brain activity in putamen correlated with magnitude of outcome prediction errors across all trials during the acquisition phase. Activations are thresholded at P < 0.001 uncorrected. (B) Correlation between outcome prediction errors and blood oxygen level-dependent activity in the two different drug states. Data in the ‘ON’ state was averaged across the two acquisition sessions performed in the scanner under this medication state and data in the ‘OFF’ state across the four acquisition sessions performed in this medication state. Error bars represent SEM. n.s. = not significant.
