Epigenetic aging is associated with aberrant neural oscillatory dynamics serving visuospatial processing in people with HIV
Figure 1. Experimental paradigm and behavioral results. (A) An illustration of the visuospatial processing task paradigm. Each trial had a fixation period lasting 2000 ms (variable ISI: 1900-2100 ms) and a stimulus-presentation period lasting 800 ms, which consisted of one of the four options displayed. Participants responded whether the checkered grid appeared to the left or to the right. (B) (Left) Reaction time (in ms) is displayed on the y-axis. There was a significant difference in reaction time by group such that people with HIV were slower to respond than controls, but they did not differ in terms of accuracy. (B) (Right) Biological age was associated with reaction time in all participants. *p < 0.05.
