Definitions:

Alpha Waves

Brain rhythms detectable by EEG, typically associated with relaxed, wakeful states, and indicating a lack of arousal in most individuals.

EEGs

Short for electroencephalograms, these are tests that measure the electrical activity of the brain and are used to diagnose and monitor neurological disorders.

REM Sleep

A sleep stage characterized by rapid eye movement, increased brain activity, and vivid dreams.

K-Complexes

Brain waves that occur during stage 2 of NREM sleep, characterized by a sudden increase in wave amplitude, and thought to aid in sleep-based memory consolidation and sleep quality.
