Abstract
The influence on sleep of alcohol (ethanol) was investigated in nine males using the correlation dimension (CD). Polysomnography (PSG) was recorded on a baseline night (BL-N) and on an ethanol (0.8 g/kg) night (Et-N). The mean correlation dimensions on Et-N, as well as on BL-N, significantly decreased from sleep stage 'awake' to sleep Stages 1, 2 and 3 and increased during rapid eye movement (REM) sleep. The mean correlation dimensions of the sleep EEG during sleep Stage 2 and those for the second sleep cycle on the Et-N were significantly higher than those on the BL-N. The changes in the correlation dimensions between sleep cycles were reduced on Et-N as compared to BL-N.
