“…These observations are in agreement with previous canine research in which day/night locomotor activity (Tobler and Sigg, 1986;Nishino et al, 1997;Siwak et al, 2003) and electroencephalogram-detected sleep/wake status (Lucas et al, 1977;Gordon and Lavie, 1984;Tobler and Sigg, 1986;Takeuchi and Harada, 2002) were measured. In the present study, all animals lived in an indoor environment and had their activity recorded while in their home pen with exposure to a 12-hour light/dark cycle.…”

Mammalian Sleep Dynamics: How Diverse Features Arise from a Common Physiological Framework

Mammalian sleep varies widely, ranging from frequent napping in rodents to consolidated blocks in primates and unihemispheric sleep in cetaceans. In humans, rats, mice and cats, sleep patterns are orchestrated by homeostatic and circadian drives to the sleep–wake switch, but it is not known whether this system is ubiquitous among mammals. Here, changes of just two parameters in a recent quantitative model of this switch are shown to reproduce typical sleep patterns for 17 species across 7 orders. Furthermore, the parameter variations are found to be consistent with the assumptions that homeostatic production and clearance scale as brain volume and surface area, respectively. Modeling an additional inhibitory connection between sleep-active neuronal populations on opposite sides of the brain generates unihemispheric sleep, providing a testable hypothetical mechanism for this poorly understood phenomenon. Neuromodulation of this connection alone is shown to account for the ability of fur seals to transition between bihemispheric sleep on land and unihemispheric sleep in water. Determining what aspects of mammalian sleep patterns can be explained within a single framework, and are thus universal, is essential to understanding the evolution and function of mammalian sleep. This is the first demonstration of a single model reproducing sleep patterns for multiple different species. These wide-ranging findings suggest that the core physiological mechanisms controlling sleep are common to many mammalian orders, with slight evolutionary modifications accounting for interspecies differences.

SUMMARY Like human narcoleptics, narcoleptic dogs display cataplexy, fragmented sleep and excessive daytime sleepiness. Cataplexy in dogs can easily be quantified using a simple behavioural bioassay, the Food Elicited Cataplexy Test. In contrast, daytime sleepiness and fragmented sleep are more difficult to measure, as long-term, labour-intensive polygraphic recordings in surgically-implanted animals are needed. In the current study, 24-h rest/activity patterns in genetically narcoleptic, asymptomatic heterozygous and control Dobermans were compared using small sized ambulatory activity monitoring devices under 12-h light/dark conditions. Control and heterozygous dogs were found to be more active during the light period than during the dark period, thus demonstrating a clear 24-h rest/activity cycle. In contrast, narcoleptic dogs were relatively inactive during the light period and did not show a clear rest/activity pattern, a result similar to that of human narcoleptics. Considering the fact that narcoleptic dogs show shorter sleep latency and sleep significantly more during the daytime than control dogs, the decrease in activity in narcoleptic dogs during the daytime is most likely a reflection of increased daytime napping in these animals. Ambulatory activity monitoring may be a useful non-invasive method for future pharmacological and developmental studies in the narcoleptic canine model.
