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.

Slow-Wave Sleep

A deep sleep stage characterized by slow brain waves, reduced muscle activity, and slowed physiological activity, facilitating restorative processes.
