Sleep

Polysomnography
Intensive study of a sleeping person involving simultaneous monitoring and recording of various physiological responses of the sleeper during the course of a night.
Electroencephalograph EEG
detect, amplify and record the electrical activity spontaneously generated by the brain during sleep and dreaming.
Value of EEG
Enables researchers to distinguish between 5 stages of sleep.
Electromyograph EMG
detect, amplify and record the electrical activity
of muscles.
Value of EMG
Identifies the systematic changes in muscular activity during a nights sleep.
Electro-oculargraph EOG
measures eye movements or eye positions by detecting, amplifying and recording electrical activity in eye muscles that control eye movements.
Value of EOG
Indicates when sleeper is in REM sleep to NREM sleep.
Video monitoring
Observable physiological responses
Value of Video monitoring
Useful for identifying activity of sufferers of sleep disorders.
Self reports
self-reported record of an individual’s sleep and waking time activities, usually over a period of several weeks
Value of Sleep Reports
Can be used to diagnose causes of sleep phenomena and disorders.

- Non rapid eye movement NREM
- Rapid eye movement REM
How long does one cycle of NREM sleep last for in adult?
70 - 90 minutes
How does a sleep cycle (including NREM and REM sleep) last for?
80 - 120 minutes
