Central mechanisms of paradoxical sleep

Brain and Development, 1984
Paradoxical sleep (PS) is composed of several characteristic "tonic" and "phasic" events. In this paper, it was shown that each of these "PS-subsystems" might be generated by distinct brainstem neuron groups and involved in the cholinergic, cholinoceptive, and monoaminoceptive mechanisms.

Paradoxical sleep deprivation induces muscle atrophy

Muscle & Nerve, 2012
AbstractIntroduction: Because paradoxical sleep deprivation (PSD) induces a catabolic hormone profile, we sought to evaluate the morphology of the tibialis anterior (TA) muscle and testosterone and corticosterone levels of paradoxical sleep–deprived rats.Methods: Three study groups of rats were established: the first group was sleep deprived for 96 h ...

NARCOLEPTIC SYNDROME AND PARADOXICAL SLEEP

Psychiatry and Clinical Neurosciences, 1966
SummaryIn order to elucidate the mechanism of the narcoleptic syndrome, the course of all‐night sleep was investigated by means of poly graphic methods or by using inducing stimuli. Further study on each symptom was performed in relation to the sleep mechanism using similar methods. Thirty‐three cases of typical narcolepsy were examined.

Paradoxical sleep and memory storage processes

Behavioral Biology, 1977
This paper advances the view that during the paradoxical sleep (PS) phase, the brain sets in motion a “chain-of-events” that is necessary for learning ability and that these events are an integral component of memory storage processes. The evidence supporting the position taken in this paper comes from experiments showing that: (1) PS deprivation (PSD),

Paradoxical sleep: Prolonged augmentation following learning

Brain Research, 1974
Abstract This experiment provides evidence that learning induces a protracted augmentation of paradoxical sleep (PS) time, lasting for at least 24 h. Albino mice are studied in a counterbalanced crossover design experiment in which each animal is used as its own baseline control and yoke control.

Prazosin increases paradoxical sleep

European Journal of Pharmacology, 1980
Prazosin 0.5 and 1.0 mg/kg i.p. induced a prompt and enduring increase in paradoxical sleep in the cat. The maximal effect, 140 percent above control was observed during the first 4 h after 1 mg/kg. In 16 h polygraphic records the respective increment was 69%.

The Thermophysiology of Paradoxical Sleep

Neuroscience and Behavioral Physiology, 2012
Paradoxical sleep (PS) is a “third” state in warm-blooded animals had humans (along with waking and slow-wave sleep) and is characterized by a high level of brain activity during deep sleep; there is a clear Russian “trace” in the discovery of PS. This review analyzes data on the interactions between PS and thermoregulation in thermally comfortable and

Rossiiskii fiziologicheskii zhurnal imeni I.M. Sechenova, 2011
Data on interactions between the paradoxical sleep (PS) and thermoregulation under thermo-comfortable and extreme conditions (in high and low temperatures, forced and spontaneous fasting, acclimation to cold and acclimation to natural winter conditions) are reviewed.
