Sleep and wakefulness in rats: probabilities of state transitions and state-to-state serial correlations in relation to circadian and ultradian phases

Richard Stephenson

This study analyzes sleep-wake state transitions in rats, finding no support for sleep homeostasis hypotheses and proposing an alternative mechanism based on transition momentum.

The role of ultradian rhythms in post-deprivationrebounds and diurnal rhythms of sleep and wakefulness in rats

Joonbum Lim, Richard Stephenson

This study investigates ultradian rhythms in sleep and wakefulness in rats after sleep deprivation, finding that rebounds in wakefulness and NREM sleep depend on full ultradian cycles and are mediated by changes in ultradian phase duration and arousal probability.
