From: Fronto-striatal dopamine D2 receptor availability is associated with cognitive variability in older individuals with low dopamine integrity

Figure 2

Relationships between fronto-striatal D2DR availability and intra-individual variability in reaction time (RT) (a), and mean RT (b), colored by subgroup membership (Class 1 = high cognition, high D2DR availability, Class 2 = low cognition, low D2DR availability, Class 3 = low cognition, high D2DR availability60). Figures display standardized residuals of each variable after controlling for sex, education, and mean RT (a), or sex and education (b) within each subgroup.
