Neural correlates of prosocial giving. Regions in which smaller gray matter volume was associated with lower prosocial giving (cool colors) and greater prosocial giving (warm colors) at p _raw < .001 (covariates included age, sex, CDR Total, diagnosis, and total intracranial volume). (a) Across all participants (N = 58), smaller volume in the right pulvinar nucleus of the thalamus was associated with lower prosocial giving. In a subset of participants (N = 35), when we included participants’ confidence ratings as an additional covariate, smaller volume in the left pulvinar nucleus of the thalamus was also associated with lower prosocial giving. (b) In the analyses of both the entire sample and the subset of participants with confidence ratings, smaller volume in left ventral striatum was associated with greater prosocial giving
