  Seasonal patterns in the daily distribution of sleep and wakefulness of the rook, Corvus frugilegus
 
 
Title: Seasonal patterns in the daily distribution of sleep and wakefulness of the rook, Corvus frugilegus
Author: Szymczak, Jadwiga T.
Appeared in: Biological rhythm research
Paging: Volume 18 (1987) nr. 1 pages 49-57
Year: 1987-05
Contents: Standard polygraphic recordings of sleep and wakefulness were carried out in the captive rook, Corvus frugilegus, in five different periods of the year under natural lighting conditions and outside air temperature. The changes in the daily amount of slow wave sleep well reflected the seasonal changes in daylength. The daily amount of paradoxical sleep was strongly affected by ambient temperature. In all the seasons studied slow wave sleep showed an increase in the course of the night. That increasing trend underwent residual seasonal changes. Paradoxical sleep decreased throughout the night, but in low ambient temperature this trend disappeared.
