Unilateral EEG activation during sleep in the Cape fur seal, Arctocephalus pusillus.
Sleep and wakefulness on the land were studied electrophysiologically in one adult female Cape fur seal (Arctocephalus pusillus). In two 24-h sessions, slow-wave sleep and paradoxical sleep averaged 27.4% and 4.6% of the total recording time. Almost 40% of the total slow-wave sleep time was accounted for episodes with well-defined interhemispheric ECoG asymmetry.
