Note.— CVLT indicates California Verbal Learning Test; IFR, immediate free recall; LDFR, long delay free recall; MMSE, Mini Mental State Examination; SDFR, short delay free recall. Data are displayed as the revelant Spearman’s rank-order partial correlation coefficient sign (+, positive; −, negative) for each brain region and test score. Note the overall frequency of negative correlation coefficients for gray matter regions and positive correlation coefficients for white matter regions.
