What is Myelin Sheath?
300

What term refers to the fact that the brain has two hemispheres and that each side supposedly has its own distinct functions?

lateralization

This sleep disorder causes individuals to suddenly fall asleep, often directly into REM sleep, at unpredictable times.

What is narcolepsy?

This tool records electrical activity in the brain and is commonly used to study sleep stages and detect abnormalities such as seizures.
