  • At the time of incentive presentation, no regions showed decreasing activity for increasing prospective gains. Statistically significant activations are those found in a priori regions of interest (familywise error, *p < 0.05) and those regions that survive whole-brain correction for multiple comparisons (at *p < 0.05). Laterality - right (R); left (L); central (C).
