Brain circuit that drives sleep-wake states, sleep-preparation behavior is identified

Stanford University School of Medicine scientists have identified a brain circuit that’s indispensable to the sleep-wake cycle. This same circuit is also a key component of the reward system, an archipelago of interconnected brain clusters crucial to promoting behavior necessary for animals, including humans, to survive and reproduce.

No sedative necessary: Scientists discover new 'sleep node' in the brain

(Medical Xpress)-A sleep-promoting circuit located deep in the primitive brainstem has revealed how we fall into deep sleep. Discovered by researchers at Harvard School of Medicine and the University at Buffalo School of Medicine and Biomedical Sciences, this is only the second “sleep node” identified in the mammalian brain whose activity appears to be both necessary and sufficient to produce deep sleep.
