Three‐dimensional clusters with significantly greater BOLD signal change to the contrast of neutral faces and the fixation cross in the placebo compared with the ketamine condition*

Cerebral region	Side	x	y	z	BA	Size
Middle occipital gyrus	L	−37	−77	−6	18	392
Precentral gyrus	L	−42	−8	43	4	336

^*Talairach co‐ordinates refer to the voxel with the maximum FPQ (fundamental power quotient) in each cluster. The total number of clusters compared between the two conditions was <200, P = 0.01. The expected number of false positive tests was <1.
