Brain regions showing lower functional connectivity strength with the posterior cingulate cortex (PCC) compared to healthy controls (HC). Top row) Cannabis-dependent individuals who do not smoke tobacco (Cs) less than HCs. Middle row) Cannabis-dependent individuals who smoke tobacco (CTs) less than HCs. Bottom row) Nicotine-dependent, cannabis-naive individuals (Ts) less than HCs. Clusters of significant differences (p < 0.001, cluster-corrected at family-wise error (FWE) of p < 0.05 and k > 40 voxels) are displayed on representative sagittal, coronal, and axial slices overlain on the standard MNI brain. Right side of the brain is depicted on the right side. L = left; R = right; mPFC = medial prefrontal cortex; Parahipp = parahippocampus.
