Sleep can follow a physiological or behavioral definition. Yokogawa Electric Corporation GS 04L52B01-01EN June. Various types of channels and also manual output. The GP10/GP20 are portable type paperless recorders.

Sleep is quickly reversible, as opposed to hibernation or coma, and sleep deprivation is followed by longer or deeper rebound sleep.Yokogawa 372142 LR4210 Flatbed Pen Recorder with Printer and Elec. In very simple animals, behavioral definitions of sleep are the only ones possible, and even then the behavioral repertoire of the animal may not be extensive enough to allow distinction between sleep and wakefulness. The physiological definition applies well to birds and mammals, but in other animals (whose brain is not as complex), the behavioral definition is more often used. Increased sensory threshold), the adoption of a typical posture, and the occupation of a sheltered site, all of which is usually repeated on a 24-hour basis. In the behavioral sense, sleep is characterized by minimal movement, non-responsiveness to external stimuli (i.e.

Animals that do not need recovery sleep after staying awake longer than usual Animal species that do not sleep at all In this manual, the terms DX1000 and DX2000 refer to the following models.If sleep were not essential, one would expect to find: IM 04L41B01-05EN iii Applicable Recorders The models listed below can be equipped with the advanced security function.

Invertebrates A cuckoo bee from the genus Nomada, sleeping. However it remains to be shown definitively whether any fish is capable of unihemispheric sleep. While some varieties of shark, such as great whites and hammerheads, must remain in motion at all times to move oxygenated water over their gills, it is possible they still sleep one cerebral hemisphere at a time as marine mammals do.

The jellyfish Cassiopea is among the most primitive organisms in which sleep-like states have been observed. Unicellular organisms do not necessarily 'sleep', although many of them have pronounced circadian rhythms. Sleep as a phenomenon appears to have very old evolutionary roots. Bees have some of the most complex sleep states amongst insects.

However, fruit flies appear to sleep, and systematic disturbance of that state leads to cognitive disabilities. Insects do not seem to exhibit REM sleep. Insects go through circadian rhythms of activity and passivity but some do not seem to have a homeostatic sleep need. Raizen et al.'s results furthermore suggest that sleep is necessary for changes in the neural system.The electrophysiological study of sleep in small invertebrates is complicated. Here, a lethargus phase occurs in short periods preceding each moult, a fact which may indicate that sleep primitively is connected to developmental processes. Elegans is another primitive organism that appears to require sleep.

Flies deprived of sleep require a longer time to learn this and also forget it more quickly. But if sugar is placed in the end of the dark tunnel, and something the flies dislike is placed in the end of the light tunnel, the flies will eventually learn to fly towards darkness rather than light. Normally, flies are attracted to light. A common method is to let the flies choose whether they want to fly through a tunnel that leads to a light source, or through a dark tunnel.

Typically fish exhibit periods of inactivity but show no significant reactions to deprivation of this condition. Fish Sleep in fish is subject of current scientific research. In honeybees, it has been shown that they use sleep to store long term memories. Sleep has been described in crayfish, too, characterized by passivity and increased thresholds for sensory stimuli as well as changes in the EEG pattern, markedly differing from the patterns found in crayfish when they are awake. In cockroaches that rest period is characterized by the antennae being folded down and by a decreased sensitivity to external stimuli.

Land vertebrates Mammals, birds and reptiles evolved from amniotic ancestors, the first vertebrates with life cycles independent of water. On the other hand, sleep patterns are easily disrupted and may even disappear during periods of migration, spawning, and parental care. A 1961 observational study of approximately 200 species in European public aquaria reported many cases of apparent sleep. For example, zebrafish, tilapia, tench, brown bullhead, and swell shark become motionless and unresponsive at night (or by day, in the case of the swell shark) Spanish hogfish and blue-headed wrasse can even be lifted by hand all the way to the surface without evoking a response. Other fish seem to sleep, however. There is also doubt about certain blind species that live in caves.

Amphibians have periods of inactivity but show high vigilance (receptivity to potentially threatening stimuli) in this state.There are significant similarities between sleep in birds and sleep in mammals, which is one of the reasons for the idea that sleep in higher animals with its division into REM and NREM sleep has evolved together with warm-bloodedness. Reptiles and amphibians In 2016, a study reported the existence of REM- and NREM-like sleep stages in the Australian dragon Pogona vitticeps. It is proposed that REM sleep evolved from short bouts of motor activity in reptiles while Slow-Wave Sleep (SWS) evolved from their basking state which shows similar slow wave EEG patterns. Daytime activity in reptiles alternates between basking and short bouts of active behavior, which has significant neurological and physiological similarities to sleep states in mammals. Up to this point, reptiles were considered the most logical group to investigate the origins of sleep. However, recent evidence of REM-like sleep in fish suggests this divergence may have occurred much earlier than previously thought.

Opinions partly differ about sleep in migratory birds. These ducks have significantly more unihemispheric sleep than those who sleep in the middle of the flock, and they react to threatening stimuli seen by the open eye. Ducks near the perimeter of the flock are likely to be the ones that first will detect predator attacks.

Bats sleep while hanging upside down. Giraffes, for example, only need to lie down for REM sleep for a few minutes at a time. Horses and other herbivorous ungulates can sleep while standing, but must necessarily lie down for REM sleep (which causes muscular atony) for short periods. Generally, they go through periods of alternating non-REM and REM sleep, but these manifest differently. Theoretically, certain types of sleep could be possible while flying, but technical difficulties preclude the recording of brain activity in birds while they are flying.Mammals have wide diversity in sleep phenomena.
