Volumes of the hippocampus and of CA4 and DG subregions showed highly significant differences as a function of both age group (Wilks’ Λ = 0.618; F 6,133 = 13.70; p < 0.001) and gender (Wilks’ Λ = 0.880; F 6,133 = 3.04; p = 0.008) as well as a significant age-by-gender interaction (Wilks’ Λ = 0.905; F 6,133 = 2.33; p = 0.036).
