Results from the ROI analysis. Fig. 3 illustrates the results from the main ROI analyses. The IFG bilaterally, and the left inferior parietal cortex showed significant increases in the BOLD response when the up arrow cue was detected in all three acquisition blocks. By contrast, the motor related ROIs all showed increased BOLD signal to up arrow cues selectively when the subsequent response was a button press. Interestingly, the SMC1 and SMC2 ROIs were also significantly deactivated when the subsequent response was the inhibition of a button press. ⁎ p < 0.05, ⁎⁎ p < 0.01, ⁎⁎⁎ p < 0.001. The Y axis is regressor β weight and error bars show the standard error of the mean.
