Cortical thinning on the lateral brain surface in HIV/AIDS. (a) Average profile of cortical thickness in AIDS patients. Right hemisphere is on the left. (b) Mean cortical thickness for matched healthy controls. (c) Average percentage thinning of the cortex in AIDS relative to healthy controls. (d) Color-coded map that shows the significance of the group difference, at each cortical point (reds indicate significant cortical thinning). The band of thinner cortex encompasses the primary sensorimotor, premotor, and parietal cortices.
