Figure 5. Statistical parametric map (SPM) showing group differences in alpha synchronization in occipital cortices and the accuracy correlation in uninfected controls.

Figure 5

(A) Uninfected controls exhibited significantly stronger alpha synchronization in occipital cortices from 2.6 to 5.0 s after the onset of the encoding grid, which corresponds to the vast majority of the maintenance period. (B) The amplitude of alpha synchronization in occipital cortices was significantly correlated with accuracy in the working memory MEG task in uninfected controls (p = 0.03), but not HIV-infected patients. The SPM has been thresholded at (p < 0.01, corrected) and is displayed following radiological convention.
