Sleeping mammalian brains show high coherence of slow-wave activity. In mouse models of Alzheimer's disease, which have abnormal levels of amyloid-β, amyloid plaques and associated memory deficits, these waves are massively impaired. This impairment is related to the previously demonstrated neuronal hyperactivity. Pharmacological manipulations that reduce hyperactivity result in the reinstatement of slow-wave coherence and in memory improvement.
