Alcohol effect on sleep electroencephalography by fast Fourier transformation

The influence of alcohol (ethanol) on sleep was investigated in 10 men. Polysomnography (PS) was recorded on a baseline night (BL‐N) and an ethanol (0.8 g/kg) night (Et‐N). On visual score rapid eye movement (REM) sleep was reduced, REM latency was prolonged on Et‐N as compared to BL‐N. Using the fa...

Description
Summary:The influence of alcohol (ethanol) on sleep was investigated in 10 men. Polysomnography (PS) was recorded on a baseline night (BL‐N) and an ethanol (0.8 g/kg) night (Et‐N). On visual score rapid eye movement (REM) sleep was reduced, REM latency was prolonged on Et‐N as compared to BL‐N. Using the fast Fourier transformation method, electroencephalographic power density of REM sleep in δ frequencies band and in the 10–12 Hz range of non‐REM sleep were enhanced. REM sleep and non‐RJEM sleep changes were prominent in the second‐half and first‐half of the night, respectively.
