Panel A: The effect of chronic binge ethanol treatment on the percent time spent in sleep-wakefulness during the 12 hr light period of post-ethanol day is described. The P and NP rats spent comparable time in all three states of behavior during the light period on post-ethanol day.
Panel B: The effect of chronic binge ethanol treatment on the percent time spent in sleep-wakefulness during the 12 hr dark period of post-ethanol day is described. As compared to NP rats, the P rats displayed a significant increase in wakefulness coupled with a significant decrease in NREM sleep. REM sleep was comparable in P and NP rats. * = p<0.05; ** =p<0.01
