Description: Results of regression analysis examining the association between individual differences in cognitive flexibility as measured with the difference between part b and a in the trail making test and individual differences in dopamine D2 receptor availability as measured with PET and the radioligand [18F]fallypride controlling for age in an adult life-span sample of healthy humans. Regression analysis included the continuous cognitive score (trail making test b-a) and age as continuous independent variables with dopamine D2-like binding potential as the dependent variable. Data collected at Vanderbilt University in the Zald lab.
