Figure 4. Relationship between HIV metrics and oscillatory alpha and theta power. Lower nadir CD4 counts (A) and lower current CD4 counts (B) were associated with stronger (i.e., more negative) oscillatory alpha power in the right medial prefrontal cortex. (C) The longer PWH had been on combination antiretroviral therapy (cART), the weaker their oscillatory theta power in the left posterior cingulate cortex. *p < 0.05.
