a

Bivariate Spearman’s rank-order correlations between Rr, Tr, Immediate LMT and Delayed LMT.

b

Partial correlations, controlling for age, gender, sample, elapsed time between MRI scan and neuropsychological assessment, years of education and APOE risk score, between memory scores and left or right HV.

c

Bivariate Spearman’s rank-order correlations between left and right HV corrected for TIV.
