Fig. 1: Connectivity increases following active ketamine infusion.

Increased connectivity between bilateral thalamus (purple) and sensory regions for [active ketamine – saline] > [placebo ketamine – saline]. There were no significant clusters for [placebo ketamine – saline] < [ketamine ketamine – saline]. A anterior, L left. The color bar shows voxel-wise z-values. Coordinates (x, y, z) are reported in MNI space. Map is thresholded using a voxel-wise cluster defining threshold of z > 3.29 (p < 0.001) and FWE-corrected cluster significance threshold of p < 0.05.
