goRT, mean reaction time on correct go trials; IES, inverse efficiency score; SSRT, stop-signal reaction time; rIFG, right inferior frontal gyrus; pre-SMA, pre-supplementary motor area. Besides the accuracy indicators, the units of the other measurements were milliseconds (ms). p < 0.05 was considered significant.
