The mean amounts (± SEMs) of 2% ethanol (left panel), 4% ethanol (middle panel), and 6% ethanol (right panel), adjusted for body weights, consumed by the spontaneously hypertensive male (SHR-M) and female (SHR-F), and Sprague-Dawley male (SD-M) and female (SD-F) rats during the continuous-access to ethanol (fade-in procedure) in Experiment 1. *indicates significant difference from SD groups at same ethanol concentration. # indicates significant difference within the same group at different ethanol concentrations.
