^F2-aThe peak was located in the postcentral gyrus. This activation overlapped with cytoarchitectonic areas 4a, 4p, 3b, and 1. Overlaps smaller than 50 mm³ are not shown. This field extended anteriorly into area 6 and posteriorly into the gyri lining the postcentral sulcus.

^F2-bThis was extending into the CMAc.

^F2-cThis extended into the left anterior cingulate cortex.

^F2-dThis also extended into the right cortex of the insula.
