Activation of basal forebrain astrocytes induces wakefulness without compensatory changes in sleep drive

AM Ingiosi, CR Hayworth, MG Frank - Journal of Neuroscience, 2023 - Soc Neuroscience
Mammalian sleep is regulated by a homeostatic process that increases sleep drive and
intensity as a function of prior wake time. Sleep homeostasis has traditionally been thought …
