The authors find that optogenetic stimulation of melanin-concentrating hormone (MCH)-expressing neurons in the lateral hypothalamus selectively extends the duration of paradoxical sleep episodes in mice. Activation of MCH fibers in the tuberomammillary nucleus leads to the release of GABA and a similar increase in paradoxical sleep stability.
