Human hypocretin and melanin concentrating hormone levels are linked to emotion and social interaction
The neurochemical changes underlying human emotions and social behavior are largely unknown. Here we report on the changes in the levels of two hypothalamic neuropeptides, hypocretin-1 (Hcrt-1) andExpand
Developmental changes in cardiorespiratory patterns associated with terrestrial apnoeas in harbour seal pups
SUMMARY During the nursing period seals undergo several physiological and behavioural changes. A key component of development is increased cardiorespiratory control, fundamental for breath-holdingExpand
Electroencephalogram asymmetry and spectral power during sleep in the northern fur seal
The fur seal (Callorhinus ursinus), a member of the Pinniped family, displays a highly expressed electroencephalogram (EEG) asymmetry during slow wave sleep (SWS), which is comparable with theExpand
Cortical Acetylcholine Release Is Lateralized during Asymmetrical Slow-Wave Sleep in Northern Fur Seals
Fur seals are unique in that they display both bilateral slow-wave sleep (BSWS), as seen in all terrestrial mammals, and slow-wave sleep with interhemispheric electroencephalogram (EEG) asymmetry,Expand
Fur Seals Display a Strong Drive for Bilateral Slow-Wave Sleep While on Land
Fur seals (pinnipeds of the family Otariidae) display two fundamentally different patterns of sleep: bilaterally symmetrical slow-wave sleep (BSWS) as seen in terrestrial mammals and slow-wave sleepExpand
Activation of the Hypoglossal to Tongue Musculature Motor Pathway by Remote Control
Reduced tongue muscle tone precipitates obstructive sleep apnea (OSA), and activation of the tongue musculature can lessen OSA. The hypoglossal motor nucleus (HMN) innervates the tongue muscles butExpand
Study of sleep in a walrus
Several behavioral and physiological adaptations have been developed in evolution of Pinnipeds allowing them to sleep both on land and in water. To date sleep has been examined in detail in eared andExpand
Monoamine Release during Unihemispheric Sleep and Unihemispheric Waking in the Fur Seal.
STUDY OBJECTIVES Our understanding of the role of neurotransmitters in the control of the electroencephalogram (EEG) has been entirely based on studies of animals with bilateral sleep. The study ofExpand
Sleep in Aquatic Species
Fully aquatic cetaceans can sleep while in motion with only one eye closed at a time. They display a unique form of sleep called unihemispheric slow-wave sleep and show no apparent indications ofExpand
Symmetrical Serotonin Release during Asymmetrical Slow-Wave Sleep: Implications for the Neurochemistry of Sleep–Waking States
On land, fur seals predominately display bilaterally synchronized electroencephalogram (EEG) activity during slow-wave sleep (SWS), similar to that observed in all terrestrial mammals. In water,Expand
