Before revision: It is one of several GABAergic sleep-promoting nuclei in the brain, which include the ventrolateral preoptic area of the hypothalamus, the nucleus accumbens core (specifically, the D2-type medium spiny neurons in the core which co-express adenosine A2A receptors), and a GABAergic nucleus in the lateral hypothalamus which co-release melanin-concentrating hormone.
