Region of interest (ROI) analysis for pro and antisaccade preparation. (A) Representation of mean BOLD signal time course for pro and anti prep for all ROIs derived from Fig. 4A. (B) Mean beta weight values for the 5th and 6th time points from the BOLD signal time course depicted in panel A (represented by the shaded bar in A). Left and right hemispheres were averaged. In ROIs where significant activation was not observed in one group, thresholds were lowered until beta weights could be obtained. Error bars represent standard error of the mean (SE). *p < .05.
