Uninfected adults exhibited significantly stronger beta ERD activity compared with HIV-infected adults in the left precentral gyrus, SMA, and a small area of the right precentral gyrus (blue areas; p < 0.01, cluster-corrected). In contrast, HIV-infected adults had significantly stronger beta ERD responses in the right (orange areas; p < 0.01, cluster-corrected). Again, an image of the task paradigm is shown in the lower left.
