title: Alcohol differentially affects c-Fos expression in the supraoptic nucleus of long-sleep and short-sleep mice.
abstract: Ethanol administration in long-sleep (LS) and short-sleep (SS) mice results in a large number of Fos-IR neurons in the supraoptic nucleus (SON) in LS, and almost no Fos-IR neurons in the same nucleus in SS mice. In contrast, isotonic saline, hypertonic saline, with or without ethanol, resulted in a similar pattern of Fos-IR in both strains. These data indicate a differential effect of ethanol on c-Fos signaling specifically in the SON. Since the LS and SS mice were specifically selected for differential sensitivity to the sedative/hypnotic effects of ethanol, this differential in c-Fos activity may be causally implicated in their differential sensitivity to ethanol.
