Final multiple regression model performed on the predictive significant variables selected by the stepwise regression using BOLD measures of both hippocampi as dependent variables and the other brain regions as independent variables scores for the five time-periods.

Abbreviations: Amg = amygdala, F sup = superior frontal gyrus, F mid = middle frontal gyrus, Hcp = hippocampus, L = left, Para = parahippocampal gyrus, PCC = posterior cingulate gyrus, Prec = precuneus, r = Bravais-Pearson coefficient, T = lateral temporal gyri, T pole = temporal pole, R = right.

r² is the total proportion of variance mediated by each predictor and the total r² is the total r² for the selected predictors with associated significance probability
