Expression of inducible transcription factors (ITFs) c-Fos and FosB was investigated during acquisition of alcohol drinking in C57BL/6J mice. A slight but statistically significant increase in c-Fos expression was found in the Edinger-Westphal nucleus (EW) of animals consuming 2% ethanol/10% sucrose for the first time. Stronger expression of c-Fos in EW was found in animals repeatedly consuming ethanol-containing solutions. These findings underscore the potential importance of EW in alcohol-related behaviors.
