Description: Results of regression analysis examining the association between individual differences in speed of processing as measured with part a of the trail making test and individual differences in dopamine D2 receptor availability as measured with PET and the radioligand [11C]FLB 457 controlling for age in an adult life-span sample of healthy humans. Regression analysis included the continuous cognitive score (trail making test part a) and age as continuous independent variables with dopamine D2-like binding potential as the dependent variable. Data collected at Yale University in the Samanez-Larkin lab.
