  1. Pearson R statistics are provided for each partial correlation between memory performance (mean recall, recall variability) and each metric (MTC, DTI, NODDI) from the whole locus coeruleus (whole), its subdivisions (rostral, caudal), and hemispheres (left, right), controlling for age and sex. Significant Bonferroni corrected effects (p < 0.025) are bolded and non-significant trends (p < 0.05) are italicized.
