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, ...
Sleep paralysis is an episode where your brain tells the body that you're still in the rapid eye movement (REM) stage of sleep in which the limbs are temporarily paralyzed (to prevent physically acting out dreams), heart rate and blood pressure rise, and breathing becomes more irregular and shallow.
