Abstract. Sleep paralysis (SP) is a phenomenon wherein individuals awaken from deep sleep but are unable to move or speak, often experiencing vivid hallucinations. This condition, attributed to the persistence of muscle atonia from rapid eye movement (REM) sleep into wakefulness, is associated with factors like sleep deprivation and irregular ...
1 kwi 2018 · In an experimental study, participants who experienced sleep paralysis in a laboratory environment showed higher diastolic and lower systolic blood pressure in sleep-onset REM periods (SOREMP; REM episodes that occur abnormally early in the sleep cycle, defined in this study as within 25 min of sleep onset) preceding a sleep paralysis episode ...
28 lut 2017 · This paralysis (postural atonia) is triggered by the pons (including the pontine reticular formation) and ventromedial medulla that suppress skeletal muscle tone during REM sleep—via inhibition of motor neurons in the spinal cord; through neurotransmitters GABA and glycine (Brooks and Peever, 2012; Jalal and Hinton, 2013).
30 sty 2024 · Sleep paralysis (SP) is a mixed state of consciousness and sleep, combining features of rapid eye movement (REM) sleep with those of wakefulness. The exact cause of SP is unknown, and its prevalence varies among the studies.
4 wrz 2023 · Sleep paralysis refers to the phenomenon in which resumption of consciousness occurs while muscle atonia of REM (rapid eye movement) sleep is maintained, leading to intense fear and apprehension in the patient as the patient lies awake without the ability to use any part of their body.
This chapter discusses a variety of sleep paralysis experiences from the perspective of enactive cognition and cultural neurophenomenology. Current knowledge of neurophysiology and associated conditions is presented, and some techniques for coping with sleep paralysis are proposed.
7 cze 2023 · Sleep paralysis is a parasomnia that occurs when the muscle atonia of rapid eye movement sleep extends into wakefulness and can be accompanied by intense fear and hallucinations. The primary neurophysiological processes that lead to sleep paralysis are well known and include alterations in the gamma-aminobutyric acid, glycine, orexin, and ...
