Figure 2.
Examined at a threshold of p < .001 uncorrected, combined with cluster p < .05, FWE corrected, the results of whole-brain covariance analysis showed higher (a) connectivity of the caudate with anterior cingulate cortex (ACC) and (b) pallidum connectivity with the cerebellum in ketamine users (KU), as compared to healthy controls (HC). Histograms plot the mean ± S.E. of the connectivity z score of each group.
