Early life sleep disruption (ELSD) voles exposed to footshock consumed high levels of ethanol immediately after shock but returned to control levels after 24 hr. (a) Ethanol intake (g/kg) 3 hr after shock or no shock in ELSD and control voles (males and females combined). ELSD voles that were shocked consumed significantly more ethanol (10% vol/vol in water) than both Control voles that were shocked and their nonshocked ELSD counterparts over the 3 hr period (Cohorts 1 and 2 combined). (b) Ethanol intake (g/kg) 24 hr after shock or no shock revealed no differences in total consumption between ELSD and controls (Cohort 1 only) over a 24 hr period. Dotted boxes correspond to data shown. Bar height is mean. Error bars ± SEM. 2BC = 2-bottle choice. N = 12–15/group/sex. * p < .05. ** p < .01.
