c-Fos expression through the rostral–caudal dimension of the nucleus accumbens, collapsed across the core and shell. Although a three-way ANOVA indicated that the two-way interaction between treatment groups and the mean ± SEM number c-Fos cells through the rostral–caudal levels of the nucleus accumbens only approached significance (F(4,48) = 2.365; p < 0.066), we probed each level of the nucleus accumbens separately for an effect of treatment on c-Fos staining. A one-way ANOVA revealed significant main effects of the treatment groups in both the rostral level (F(2,48) = 5.230; p< 0.009) and caudal level (F(2,48) = 7.455; p < 0.002) but not in the middle level (F(2,48) = 1.744; p> 0.1) of the nucleus accumbens. Different lettersindicate significant differences between groups.
