| Abstract: | Serial BAEPs and polysomnograms were recorded during nocturnal sleep in 8 normal subjects. Wave V latency and the I-V interval were found to increase significantly during stages II, III + IV and paradoxical sleep when compared to waking. Trend curves of BAEP latencies showed that these shifts were independent of sleep stages and reversed at the end of the night. BAEP changes were found to be related to physiological hypothermia during the night. |
