VOI time courses and functional correlations. A, Activation time courses taken from the right MPFC VOI for +$5.00 gain trials of varying probabilities (*, 80 vs 20% probability of success; p < 0.05; two-tailed t test). B, Correlation of percentage hit estimate for high- versus low-probability trials with percentage signal change in the right MPFC VOI for high- versus low-probability +$5.00 gain trials (lag, 4 s; r = 0.51; p < 0.05; one-tailed). C, Activation time courses taken from the right NAcc VOI for gain trials of varying magnitudes (**, +$5.00 vs +$1.00 and +$0.00; *, $1.00 vs $0.00; p < 0.05; two-tailed t test). D, Correlation of self-reported positive arousal in response to +$5.00 cues with percentage signal change in the right NAcc VOI in response to +$5.00 cues (lag, 4 s; r = 0.52; p < 0.05; one-tailed). ant, Anticipation; rsp, response; Prob, probability; MD, mean-deviated. Error bars represent SEM.
