Table 1. Working Memory Performance and Brain Morphometry.

Panel A shows partial correlations of a gray matter volume in segmented regions (based on Desikan atlas) with 2-back accuracy controlling for age and total intracranial volume. Only regions with significant p-values after FDR are included (q < .05). Panel B shows a summary of clusters in voxelwise analysis of gray matter volume. Coordinates of peak significance provided in Montreal Neurological Institute space (X Y Z). CWP = cluster-wise p-value.
