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 ...

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).
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.
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 ...
16 sty 2018 · The physiology of REM sleep is associated with increased blood pressure, heart rate, and breathing. The activities of neurons in REM sleep are usually similar when an individual is awake, and sometimes, REM sleep may be associated with more neuronal firing, especially in the pons, lateral geniculate nucleus, and occipital cortex.[ 3 ]
26 lip 2024 · 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 sleep patterns. While isolated episodes of SP are generally benign, recurrent episodes may warrant clinical attention, particularly when accompanied by distressing ...
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.
