Slow wave sleep, often lumped with non-REM sleep, features distinct brain activity patterns characterized by sweeping waves across large areas of the brain. Neuromodulators like acetylcholine, norepinephrine, and serotonin play crucial roles in regulating which brain circuits are active during this phase, akin to curating a playlist that influences the overall mood and function of neural activity. Understanding these dynamics can enhance our grasp of sleep's impact on health and cognition.
