Executive performance is related to regional gray matter volume in healthy older individuals

Individual differences in executive functioning and brain morphology are considerable. In this study, we investigated their interrelation in a large sample of healthy older individuals. Digit span, trail‐making, and Stroop tasks were used to assess different executive subfunctions in 367 nondemented community‐dwelling individuals (50–81 years). Task performance was analyzed relative to brain structure using voxel‐based morphometry, corrected for...
