Figure 6. — Functional parcellation of fronto-opercular cortex VOI into rAI and rIFC clusters using four different features. The four features used in the clustering procedure were as follows: a, VOI time series; b, intrinsic connectivity; c, task-evoked hemodynamic response on Successful Stop (SuccStop) trials in SST1; and d, task-evoked hemodynamic response on SuccStop trials in SST2. The two leftmost columns display volume and surface rendering of the two clusters encompassing the rAI and rIFC. The middle column shows histograms demonstrating the stability of voxel assignment to each cluster within the VOI. The two rightmost columns display two thresholded clusters obtained by including voxels in the VOI that have the top 10, 20, 30, or 40% stability for assignment into each cluster.
