Explanation:
Electroencephalography functions by capturing the brain's electrical activities. Therefore, for an analysis of REM versus slow wave sleep, the electroencephalograph is the suitable method. It documents the brain's electrical activity over time, allowing for monitoring and diagnosing sleeping disorders, states of anesthesia, comas, brain death, and other conditions, including epilepsy.
