Effect of rearing condition on forced and two-bottle choice continuous access ethanol self-administration. A. Bar graph illustrating the effect of rearing condition on daily ethanol intake during a three day forced exposure procedure in which 10% ethanol was the only solution available. (*, significant difference between STD and GH rats; Ψ, significant difference between STD and SI rats; P < 0.05). B. Average daily ethanol intake during a five day, two-bottle choice drinking assay (10% ethanol/water) conducted immediately following the three day forced procedure. *, significant difference between GH and SI rats; Ψ, significant difference between GH and STD rats; P < 0.05).
