The full extent of left BA6 activation for EA × Drug (CORT vs. Placebo) includes both SMA and premotor cortex (PMC), and peak significance falls in PMC. Due to significant main effect of EA on CORT day in SMA and for theoretical reasons (24), we also report coordinates for the local maxima in SMA alone.
