What are the 4 functions of sleep?
- Conserve energy
- Enhance survival / adaptation
- Restorative / repair of injury (NREM)
- Aid learning / memory consolidation (REM)
How much sleep do adults need?

What are the three components of a Polysomnography?
– Electroencephalogram (EEG)
– Electrooculogram (EOG)
– Electromyogram (EMG)
What does an Electroencephalogram (EEG) measure?
measures and records the electrical activity of your brain through difference in electrical potential between pairs of electrodes placed on the scalp.
What does an Electrooculogram (EOG) measure?
measuring the corneo-retinal standing potential that exists between the front and the back of the human eye
What does an Electromyogram (EMG) measure?
measures muscle response or electrical activity in response to a nerve’s stimulation of the muscle.
