Fig. 2.

Cortical thinning on the medial brain surface in HIV/AIDS. The same set of maps is shown as in Fig. 1 but visualizing the medial surfaces of the brain hemispheres. Shown are the average profile of cortical thickness in AIDS patients (a), mean cortical thickness for matched healthy controls (b), the average percentage thinning of the cortex in AIDS relative to healthy controls (c), and the significance of the group difference at each cortical point (d) (red indicates significant cortical thinning). Primary sensorimotor and frontal cortices are thinner on the medial wall, as are the primary visual cortices.
