To use the term paradoxical sleep in its widest sense.

The cause could be based on the necessity for the brains to rid themselves of programming, by the means of paradoxical sleep.

REM or paradoxical sleep is universal among mammals.

During paradoxical sleep, no erections occur, and the penile muscles share the characteristics of the rest of the body.

What are the particular psychological effects, if any, of selective deprivation of REM or paradoxical sleep?

Different populations of the pontis oralis have displayed discharge patterns which coordinate with phasic movements to and from paradoxical sleep.

Approximately one hour after the onset of sleep, rapid eye movements beneath the closed lids occur (termed "paradoxical sleep" ), usually lasting about twenty minutes.

The first - rapid eye movement sleep (REM), dream sleep, paradoxical sleep - appears to be associated with dreaming.

Rapid eye movement sleep, or REM sleep (also known as paradoxical sleep), accounts for 20-25% of total sleep time in most human adults.

For historical reasons, non-dreaming sleep is electroencephalographically characterized as "slow wave sleep," and the dream state as '-'paradoxical sleep."

During REM, the activity of the brain's neurons is quite similar to that during waking hours; for this reason, the REM-sleep stage may be called paradoxical sleep.

People wake more easily during the light paradoxical sleep, and take longer to fall into the more restful deeper orthodox sleep, especially if they are under stress or in an unfamiliar environment.

This level is also referred to as paradoxical sleep because the sleeper, although exhibiting EEG waves similar to a waking state, is harder to arouse than at any other sleep stage.

Intermittent short "deep sleep" phases while lying are characterized by the giraffe bending its neck backwards and resting its head on the hip or thigh, a position believed to indicate paradoxical sleep.

Some studies suggest a link between DSIP and slow-wave sleep (SWS) promotion and suppression of paradoxical sleep, (PS) while some studies show no correlation.

Lyubov with interest, and Lepennon said, "I've just been reading your report on the conscious control of paradoxical sleep among the Athsheans, Dr. Lyubov," which was pleasant, and it was pleasant also to be called by his own, earned title of doctor.

If they caught up with their normal sleep at night, that prevented them from catching up with the REM or paradoxical sleep, whose 120-minute cycle ruled their life both day and night, and could not be fitted in to the Terran workday.

He described the electroencephalogram signs of cerebral death in 1959, and in 1961 categorized sleep into two different states: telencephalic (slow wave) sleep and rhombencephalic sleep (paradoxical sleep, known as REM sleep in English-language writings on the subject).

His works, and those of his team, have brought about the discovery of paradoxical sleep and to its individualisation as the third state of functioning of the brain in 1959, to the discovery of its phylogenesis, of its ontogenesis and its main mechanisms.

Activity in giant cells in the pontine brainstem have been shown to precede eye movements in REM sleep in animals (or paradoxical sleep, as it is called in rodents and cats) while there is no evidence that cortical activity can influence these cells' discharges.
