Generic brain activation (GBAM) during placebo and ketamine infusion in response to presentation of alternating blocks of emotionally neutral faces and fixation crosses in eight healthy male volunteers. The left side of the brain is shown on the right side of the image, and vice versa. The probability threshold for activation was P ≤ 0.004. Eight transverse brain slices are shown from 18 mm below to 20 mm above the transcallosal plane. During placebo infusion, significant BOLD signal change was demonstrated predominantly within occipitotemporal (BA 18, 37, 38) and prefrontal regions (BA 11, 47). During ketamine infusion, significant BOLD signal change was demonstrated predominantly within occipitotemporal regions (BA 37, 21, 22).
