Describes the effects of acute ethanol treatment on sleep-wakefulness

Panel A: Acute ethanol treatment at dark onset produced a significant increase in NREM sleep (*= p<0.05; paired t test) with a concomitant decrease in wakefulness (** = p<0.01; paired t test) during the dark period (first 12 hr) as compared to sleep-wakefulness following water treatment. REM sleep remained unaffected.

Panel B: In addition to increase in NREM sleep, ethanol treatment significantly reduced the latency to NREM sleep (*= p<0.05; paired t test).

Panel C: There was no change in the amount of time spent in any behavioral state during the next 12 hour (light period).
