Depicts the mean (± SEM) number of lever responses in Wistar male and female AIE (left panels) and CON (right panels) rats given aCSF (top panels), 75 mg% (middle panels) or 100 mg% EtOH (bottom panels) to self-administer directly into the posterior VTA. # indicates significantly more responding on the active lever than that observed in aCSF controls, AIE > CON and discrimination between levers. * indicates significantly more responding on the active lever than that observed in aCSF controls, AIE > CON males and discrimination between levers.
