Nicotine accelerates the escalation of alcohol self-administration, associated with Fos induction in the central amygdala, and nicotine treatment induces Fos in the basolateral amygdala. Top, Number of Fos-immunoreactive nuclei per millimeter squared in the CeA. Bottom, Number of Fos-immunoreactive nuclei per millimeter squared in the BLA. *p < 0.05, different from the other groups; n = 6–8 per group.
