THE SCIENCE OF SLEEP
(From Royce's Footnotes)
I have had the fruitful opportunity to receive a lecture on the technicalities of sleep, sponsored by my company, Tropicana Corporation Berhad.The speaker is also known as a sleep doctor, or sleep specialist, which can also be your GP or Ear, Nose & Throat specialist. There is also the American Board of Sleep Medicine - http://absm.org/ to understand a collective of Sleep scholars.
R.E.M - Rapid Eye Movement
There are 5 stages of REM sleep and we begin our sleep by entering heavier, uninterrupted sleep at the start and progress into longer alternating intervals of light REM sleep and Deep (Non-REM sleep).
TOOLS OF THE TRADE
(PSG)http://www.webmd.com/sleep-disorders/guide/polysomnogram
EMG (electromyogram) to record muscle activity such as face twitches, teeth grinding, and leg movements; it also helps in determining the presence of REM stage sleep.
EOG (electro-oculogram) to record eye movements; these movements are important in determining the different sleep stages, particularly REM stage sleep.
Nasal airflow sensor to record airflow
