“…Very shortly after, Michel Jouvet in Lyon, France, as well as other workers over the years, reported that REM sleep episodes occurred in all mammalian species investigated and was seen also in other vertebrates, but in limited amounts (Jouvet et al 1959;Jouvet and Valatx 1962;Ruckebusch 1962;Adey et al 1963;Faure et al 1963;Roldan et al 1963;Hartmann et al 1967;Shurley et al 1969;Cicala et al 1970;Schlehuber et al 1974;Latash and Galina 1975;Allison et al 1977;Siegel et al 1996Siegel et al , 1999. REM sleep was shown to be a universal phenomenon in mammals and dream sleep in humans could no longer be relegated solely to the occult or to the psychoanalytic couch.…”

Brain mechanisms that control sleep and waking

This review paper presents a brief historical survey of the technological and early research that laid the groundwork for recent advances in sleep-waking research. A major advance in this field occurred shortly after the end of World War II with the discovery of the ascending reticular activating system (ARAS) as the neural source in the brain stem of the waking state. Subsequent research showed that the brain stem activating system produced cortical arousal via two pathways: a dorsal route through the thalamus and a ventral route through the hypothalamus and basal forebrain. The nuclei, pathways, and neurotransmitters that comprise the multiple components of these arousal systems are described. Sleep is now recognized as being composed of two very different states: rapid eye movements (REMs) sleep and non-REM sleep. The major findings on the neural mechanisms that control these two sleep states are presented. This review ends with a discussion of two current views on the function of sleep: to maintain the integrity of the immune system and to enhance memory consolidation.

“…To the best of our knowledge, no study has yet investigated sleep homeostasis in marsupials. Some (but few) studies have investigated (1) the behavior and/or electrophysiology of SWS and REM sleep in marsupials, notably the red kangaroo ( Megaleia rufa ) [ 50 ], common opossum ( Didelphis marsupialis ) [ 51 , 52 ], little water opossum ( Lutreolina crassicaudata ) [ 53 ], and brushtail possum ( Trichosurus vulpecula ) [ 54 ]; (2) the influence of food distribution on sleep and circadian rhythm of the long-nosed potoroo ( Potorous tridactylus ) [ 55 ]; and (3) the ontogenesis of sleep states in the North American opossum ( D . virginiana ) [ 56 ].…”

Study Objectives In this study, we (1) describe sleep behaviour and architecture, and (2) explore how sleep is regulated in dusky antechinus (Antechinus swainsonii), a small insectivorous marsupial. Our aim is to provide the first investigation into sleep homeostasis in a marsupial. Methods Wild-caught male dusky antechinus (n = 4) were individually housed in large indoor cages under a natural photoperiod of 10.5 h light / 13.5 h dark. Continuous recordings of EEG, EMG, and tri-axial accelerometry were performed under baseline conditions and following 4-h of extended wakefulness. Results Antechinus engage in SWS and REM sleep. Some aspects of these states are mammal-like, including a high amount (23%) of REM sleep, but other features are reminiscent of birds, notably, hundreds of short sleep episodes (SWS mean: 34 s; REM sleep: 10 s). Antechinus are cathemeral and sleep equally during the night and day. Immediately after the sleep deprivation ended, the animals engaged in more SWS, longer SWS episodes, and greater SWS SWA. The animals did not recover lost REM sleep. Conclusions Sleep architecture in dusky antechinus was broadly similar to that observed in eutherian and marsupial mammals, but with interesting peculiarities. We also provided the first evidence of SWS homeostasis in a marsupial mammal.
