Tryptamine from wake-active monoaminergic neurons regulates sleep homeostasis

by Clinical Neuropsychologist Online | Friday, June 19, 2026 | Neuroscience

Nature Neuroscience, Published online: 19 June 2026; doi:10.1038/s41593-026-02332-xCao et al. identify tryptamine as a sleep signal in mice. Wake-active monoaminergic neurons release tryptamine, which binds to GPR139 in POA neurons that suppress wake-promoting...
