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 · Sleep paralysis involves a period of time at either sleep onset or upon awakening from sleep during which voluntary muscle movements are inhibited. Ocular and respiratory movements remain unaltered and perception of the immediate environment is clear [1].
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.
7 lip 2012 · We studied trigeminal motoneurons and the masseter muscles they innervate because this motor system experiences typical REM paralysis and contributes to sleep pathologies such as RBD (Schenck and Mahowald, 2002; Burgess et al., 2008; Brooks and Peever, 2011).
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 ...
