Document Summary
Intro: many aspects of your physiology and behavior have circadian rhythms. Even behaviors have a rhythm. : your body uses light information to time sleep. What is sleep: you spend 1/3 of your life asleep, originally thought of as a passive state of immobility with Lack of perception and consciousness: now we know: Sleep is composed of different states of brain activity. Some perception: wake up faster in response to your own name than the names of others. How do we measure sleep: electroencephalogram (eeg): records brainwaves: sum of electrical activity over an area of cortex, electrooculogram (eog): records eye movements during sleep, electromyogram (emg): detects activity in neck muscles during sleep o o o. Rem (paradoxical) sleep- bodies are completely frozen even though our minds are fully active. Why do we sleep: recuperation theory: restore homeostasis. Restore the physiological processes that have been altered during wakefulness: circadian theory: adaptive response.
