- Behavioral aspects of sleep in bottlenose dolphin mothers and their calvesOleg Lyamin
UCLA and VA GLAHS Sepulveda, CA, United States
Physiol Behav 92:725-33. 2007..We hypothesize that episodes of EEG slow wave activity at this time are likely to be brief, fragmenting EEG defined sleep into short episodes...
- Electroencephalogram asymmetry and spectral power during sleep in the northern fur sealOleg I Lyamin
UCLA and VA GLAHS, Sepulveda, CA 91343, USA
J Sleep Res 17:154-65. 2008..2-4 and 12-16 Hz. As shown in this study, the degree of EEG asymmetry and the frequency range in which it is expressed during SWS in fur seals are profoundly different from those of terrestrial mammals and birds...

- Regional differences in cortical electroencephalogram (EEG) slow wave activity and interhemispheric EEG asymmetry in the fur sealOleg I Lyamin
UCLA and VA GLAHS, Sepulveda, CA, USA
J Sleep Res 21:603-11. 2012..The remaining episodes can be described as episodes of bilateral SWS with a local activation in one cerebral hemisphere...
- Sleep and wakefulness in the southern sea lionOleg I Lyamin
Severtsov Institute of Ecology and Evolution, Russian Academy of Sciences, 33 Leninsky Prospect, 117071 Moscow, Russia

- Relationship between sleep and eye state in Cetaceans and PinnipedsO I Lyamin
Department of Psychiatry, School of Medicine, UCLA and Neurobiology Research 151A3, VAGLAHS Sepulveda, North Hills, California 91343, USA
Arch Ital Biol 142:557-68. 2004....
- Unihemispheric slow wave sleep and the state of the eyes in a white whaleO I Lyamin
Severtsov Institute of Ecology and Evolution, 33 Leninsky Prospect, Moscow, Russia
Behav Brain Res 129:125-9. 2002..Therefore, eye state alone may not accurately reflect sleep state in Cetaceans. Our data support the idea that unihemispheric sleep allows Cetaceans to monitor the environment...
- Fur seals display a strong drive for bilateral slow-wave sleep while on landOleg I Lyamin
Department of Psychiatry, School of Medicine, University of California Los Angeles and Neurobiology Research 151A3, Veterans Affairs Greater Los Angeles Healthcare System, North Hills, California 91343, USA
J Neurosci 28:12614-21. 2008..These data indicate that fur seals display a homeostatic response to the loss of SWS and that alternating SWS in the two hemispheres does not adequately compensate for the absence of BSWS...
- Cortical acetylcholine release is lateralized during asymmetrical slow-wave sleep in northern fur sealsJennifer L Lapierre
Department of Psychiatry, School of Medicine, University of California Los Angeles and Neurobiology Research, Veterans Affairs Greater Los Angeles Healthcare System, North Hills, California 91343, USA
J Neurosci 27:11999-2006. 2007..These findings demonstrate that cortical ACh release is tightly linked to hemispheric EEG activation...
- Cetacean sleep: an unusual form of mammalian sleepOleg I Lyamin
Department of Psychiatry, University of California, Los Angeles, Neurobiology Research 151A3, Sepulveda VAMC, 16111 Plummer Street, North Hills, CA 91343, USA
Neurosci Biobehav Rev 32:1451-84. 2008..Aspects such as sentinel functions and breathing are likely to be proximate evolutionary phenomenon of this form of sleep...
- Behavioral sleep in the walrusJulia P Pryaslova
Utrish Dolphinarium Ltd, 33 Leninsky Prospect, Moscow 119071, Russia
Behav Brain Res 201:80-7. 2009..Data indicate that the pattern of sleep and breathing in walruses is similar to the Otariidae seals while on land and the Phocidae seals while in water...
