From: Characterization of basal ganglia volume changes in the context of HIV and polysubstance use
POLY + group regressions of basal ganglia gray matter volume and substance use duration. (A) Statistical map of z-scores indicating reduced gray matter (GM) as a function of opioid use duration in the HIV-/POLY + group; z-planes = -16, -10, -4, 2, 8, 14 in MNI space; p < 0.05 FWE. R = right hemisphere, L = left hemisphere; (B) Statistical map of z-scores indicating increased GM as a function of stimulant use duration in the HIV + /POLY + group; z-planes = -10, -6, -4, 0, 4, 8 in MNI space; p < 0.05 FWE. R = right hemisphere, L = left hemisphere. (C) Depiction of basal ganglia ROI masks that were used for regression analyses with substance use duration, shown here overlaid on the SPM152 template for visualization.
