Document Summary
Biology of sleep: consciousness: our subjective experience of the world, our bodies, and our mental perspectives, circadian rhythm: cyclical changes that occur on a roughly 24-hr basis in many biological processes (ex. Hormone release, body temperature: biological clock: the scn (suprechiasmatic nucleus) on the hypothalamus, triggers our sense of fatigue (via increasing melatonin, disruptions: Night shifts: every time you ask your clock to change, it interrupts the rhythm. This causes shift workers to be more prone to illness, etc. Stages of sleep and dreaming: measuring sleep: eeg, eog, emg, stages: (cycle through every 90min, non-rem: (no eye movements, less dreaming) Stages 1-4: rem: (paradoxical sleep) stage 5, eye movements, vivid dreaming. No muscle tone rem sleep cuts off your body activity from the brainstem down. Rem rebound the longer you stay awake, the longer the time it will take to get rem sleep back. When they are overly emotional, they will trigger the cataplexy event.
