Glucocorticoids Are Not Responsible for Paradoxical Sleep Deprivation-Induced Memory Impairments

Sleep, 2008
Study Objectives: To evaluate whether paradoxical sleep deprivation-induced memory impairments are due to release of glucocorticoids, by means of corticosterone inhibition with metyrapone.Design: The design was a 2 (Groups [control, paradoxical sleep ...

A Paradoxical Kind of Sleep in Drosophila melanogaster

Current Biology, 2021
The dynamic nature of sleep in many animals suggests distinct stages that serve different functions. Genetic sleep induction methods in animal models provide a powerful way to disambiguate these stages and functions, although behavioral methods alone are insufficient to accurately identify what kind of sleep is being engaged.

Paradoxical sleep and depth perception

Biological Psychology, 1978
It has been hypothesised that one possible function of paradoxical (REM) sleep is the maintenance of facilitation of co-ordinated eye movements. A prediction from this hypothesis is that binocular depth perception will be more accurate at the end of periods of paradoxical sleep than at the beginning.

The nature of the paradoxical phase of sleep

Neuroscience Translations, 1970
1. Paradoxical sleep is a complex phenomenon which can be divided into three stages: 1) the stage of general activation, or desynchronization of slow activity in all areas of the brain, 2) the stage of predominance of the hippocampal δ-rhythm and 3) the stage of predominance of the hippocampal ϕ-rhythm.

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

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.
