During sleep, the major neuromodulators\u2014norepinephrine, acetylcholine, serotonin, and dopamine\u2014exhibit synchronized fluctuations with a periodicity of ~50 seconds. These oscillations appear as recurrent bursts of fast (10 to 30 hertz) electroencephalography activity and are phase-coupled to cerebrospinal fluid flow. Neuromodulators are vasoactive agents and drive slow vasomotion, which provide the mechanical force that supports glymphatic clearance of metabolic waste. Disruption of neuromodulator signaling, as seen in psychiatric disorders, cardiovascular disease, aging, or with commonly prescribed drugs, impairs clearance of neurotoxic proteins, including amyloid-\u03b2 and tau.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>During wakefulness, neuromodulators operate largely independently to support behavior and cognition.
