Correlation between nonlinearity of probabilities weighting and D1 binding in the striatum (N = 18 subjects). A, Image showing regions of correlation between nonlinearity parameter of weighting function and D1 binding in the striatum. The bar shows the range of the correlation coefficient. B, Plots and regression line of correlation between α (nonlinearity parameter) and binding potential of the putamen (r = 0.66, p = 0.003).
