Figure 3.

Z-scores statistical maps of significant brain–behavior association between estimates of functional connectivity of striatal seeds and positive psychotic and dissociative symptoms caused by ketamine infusion, displayed at P<0.05 (FWE cluster corrected). For visualizing purposes with the midbrain (a and b), ventral thalamus/subthalamic nucleus (c) and medial prefrontal cortex (d and e), parameter estimates were extracted from peak voxels in the shown brain maps and correlated with symptom change scores. Results remained significant after the exclusion of outliers.
