Correlations between brain structure and mean z-scores for Immediate and Delayed verbal memory recall for the whole group (x-axis runs from z = −2 to 2 in increments of 1). ^†trend (.05 < p < .08), *p < .05, **p < .01; DLPFC: dorsolateral prefrontal cortex; IFG: inferior frontal gyrus, FA: fractional anisotropy (y-axis runs from FA = .3 to .7 in increments of .1), MD: mean diffusivity. Hippocampus (y-axis runs from −1000 to 1000 in increments of 500), IFG and DLPFC (y-axis runs from −15,000 to 15,000 in increments of 5000) are volumes (mm³) controlled for intracranial volume.
