Delayed reward choice (%) in response to ethanol/saline challenges in younger adult rats (adolescent-exposed rats; A) or older adult rats (adult-exposed rats; B) regardless of previous CIE/water exposure.*p < 0.05, significant difference between saline and 1 g/kg ethanol (Fisher's LSD test). ^p < 0.05, significant difference between saline and 0.5 g/kg ethanol (Fisher's LSD test). The delayed reward choice (%) in younger adult (adolescent-exposed) rats compared with older adult (adult-exposed) rats in response to saline (C), 0.5 g/kg ethanol (D), and 1.0 g/kg ethanol (E) challenges is shown. #p < 0.05, significant difference between younger and older adult rats independent of previous CIE/water exposure (LSD test). The data are expressed as mean ± SEM.
