Aquatic mammals (i.e., Cetaceans, eared seals and manatees) and birds show interhemispheric asymmetries (IA) in slow-wave sleep-related electroencephalographic (EEG) activity, suggesting that the depth of sleep differs between hemispheres. In birds, an association between unilateral eye closure and IA has been reported in five species from three orders (i.e., Galliformes, Charadriiformes, and Anseriformes). Moreover, unilateral eye closure has been observed during behaviorally defined sleep in…

Eye state asymmetry during aquatic unihemispheric slow wave sleep in northern fur seals (Callorhinus ursinus)
The findings document the extent of visual monitoring of both eyes during USWS and support the idea that USWS allows intermittent visual vigilance, which may also be the case in cetaceans.
Electroencephalogram asymmetry and spectral power during sleep in the northern fur seal
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.

The EEG appeared relatively desynchronized and symmetrical between the two hemispheres when the animal was awake during recovery from pentothal-halothane anesthesia as well as during waking periods when one or both of the animal’s eyes were covered by an opaque rubber suction cup.

In dolphins, eared seals, and manatees, unihemispheric sleep allows them to have the benefits of sleep, breathing, thermoregulation, and vigilance, but in domestic chicks, antipredation vigilance is the main function of uni Hemispheric Sleep, and it is suggested that they involve the interaction of structures of the hypothalamus, basal forebrain, and brain stem.
Increased EEG spectral power density during sleep following short‐term sleep deprivation in pigeons (Columba livia): evidence for avian sleep homeostasis
The mammalian‐like increase in EEG spectral power density across both low and high frequencies, and the increase in time spent in REM sleep following sleep deprivation suggest that some aspects of avian and mammalian sleep are regulated in a similar manner.

Wavelet analysis of EEG, recorded from symmetrical areas of caudomedial nidopallium during rest, passive and active wakefulness and movements showed that the major rhythmical EEG component was confined to low-frequency range in all four states.
Multi-channel EEG recordings during sleep in juvenile zebra finches
Significant changes in the neural signature of sleep during development in an avian brain that are remarkably similar to age-dependent changes that occur in mammals are revealed.
Local Aspects of Avian Non-REM and REM Sleep
Collectively, the local aspects of sleep described in birds and mammals reveal that wakefulness, NREM sleep, and REM sleep are not always discrete states.
Local sleep homeostasis in the avian brain: convergence of sleep function in mammals and birds?
After staying awake watching David Attenborough's The Life of Birds with only one eye, SWA and the slope of slow waves increased only in the hyperpallium—a primary visual processing region—neurologically connected to the stimulated eye, providing the first electrophysiological evidence for local sleep homeostasis in the avian brain.
Sleep-Related Electrophysiology and Behavior of Tinamous (Eudromia elegans): Tinamous Do Not Sleep Like Ostriches
Sleep in the elegant crested tinamou, a small Palaeognath bird that more closely resembles Neognath birds in size and their ability to fly, is examined, finding the absence of a mixed REM sleep state in tinamous calls into question the idea that this state is primitive among Palae Cognath birds and therefore birds in general.

Facultative control of avian unihemispheric sleep under the risk of predation
The behavioral and social aspects of sleep are described in a captive school of four Pacific white-sided dolphins at Long Marine Lab at the University of California at Santa Cruz for 32 nights to suggest that this allows sleep to proceed while allowing dolphins to maintain visual contact with group members.

There are considerable number of publications on the EEG during both pre- and post-natal growth in birds, especially in chicks, because they are excellent material for recording and analyzing the development of the electrical activities of the brain.
Onset of cerebral electrical activity associated with behavioral sleep and attention in the developing chick.
Electroencephalographic patterns associated with sleeping postures show more conspicuous developmental changes than those associated with attention, and the cyclic episodes of activated sleep are less distinct and the span of attention is more brief.

Comparative Neuropsychology of the Dual Brain: A Stroll through Animals' Left and Right Perceptual Worlds
Data is presented showing how preferential use of the left and right eyes influences visual discrimination learning and detour behavior in chicks; similarities with detour tests performed in fish and evidence for asymmetries in eye use in animals with larger binocular overlap are discussed.
