Flexibility in the striatum relates to learning performance within-subjects. A, Mixed-effects model fit for the association between network flexibility in an a priori striatum ROI and learning performance. The black line represents the fixed effect estimate and the gray band represents the 95% confidence interval for this estimate. Color lines are predictions based on subject-level random effects estimates of the flexibility–performance relationship. B, This effect was not distinguishable across regions of the striatum (bar plots and error bars represent estimates and SEs from separate mixed-effects models for each ROI).
