Brain regional numbers of c-Fos-positive neurons in Alcw2 congenic and background strain mice. Congenic and background strain (D2) mice were administered 4 gm/kg ethanol (n = 14 and 16, respectively) or saline control (n = 5 per strain). Seven hours later, the brains were removed and processed for immunohistochemical analysis. Values represent the number of c-Fos-immunoreactive neurons (mean ± SEM) in representative sections. Significant effects of treatment (T) and strain (S), based on the results of Kruskal–Wallis one-way ANOVA, are indicated.
