Figure 2. Study 1: correlations between average ethanol intake (g/kg/day) and the mineralocorticoid nuclear receptor gene NR3C2 expression in the central nucleus of the amygdala (A, B) in rhesus macaques.

Ethanol intake is shown as an average during the second 6 months block (A) and over the entire 12 months period (B) of ethanol self-administration. There was a significant correlation between the expression of NR3C2 in the CeA and ethanol intake at both the second block of 6 months (A; r2 = 0.48; p = 0.008) and the overall 12 months (B; r2 = 0.33; p = 0.042).
