Color-coded statistical parametric maps showing areas where task-related activity during continue trials increased with stop probability. a, The dorsal ACC, right insula and adjacent IFG, left middle frontal gyrus, right thalamus, left and right IPC (supramarginal gyrus, area PF), and right superior frontal gyrus show a linear increase in activity with increasing stop probability during “continue” trials (one-sample t test, n = 18). All maps are thresholded at an uncorrected p < 0.001. Peak z scores and the corresponding stereotactic coordinates are listed in Table 1. b, An ROI analysis in STN revealed a bilateral increase in activity with stop probability after SVC. For illustration purposes, we show the unthresholded SPM in the bilateral STN mask used for the SVC.
