Significant activity p < 0.0001 (uncorrected) related to SCR events. A, Activity occurring uniquely (−4.2 sec) before skin conductance events (peaks of skin conductance responses); B, activity occurring after SCR events (+4.2 sec) not related to activity preceding SCR events; C, brain regions active both before and after SCR events: conjunction analysis of A and B. L, Left; R, right.
↵F2-a Coordinates are given for the stereotactic space of Talairach and Tournoux (1988).
↵F2-b Corrected significance p < 0.05. Data is exclusively masked by F-contrast of reward-related contrasts of the task (p < 0.0001, uncorrected). Extent threshold of 20 voxels used.
