^aRelationship between gray matter density and flumazenil BP_ND in regions showing a significant relationship in the Duncan et al. (2013) study. This table replicates the weighted least square (WLS) regression analysis done in Duncan et al. (2013) to investigate the relationship between gray matter density and flumazenil BP_ND in our healthy control group (N = 25), in regions from the Jülich histological atlas.

^bSignificant with cluster-level correction across the whole brain at p < 0.05.
