Î³-Hydroxybutyric acid (GHB), also known as 4-hydroxybutanoic acid, is a naturally occurring neurotransmitter and a psychoactive drug. Chemically closely related to GABA, it acts on the GABA receptor and on the GHB receptor. GHB has been used in a medical setting as a general anesthetic, for cataplexy, narcolepsy, and alcoholism. It is also used illegally as an intoxicant, to try to increase athletic performance, and as a date rape drug. It is commonly used in the form of a salt, such as sodium Î³-hydroxybutyrate (Na.GHB, sodium oxybate, or Xyrem) or potassium Î³-hydroxybutyrate (K.GHB, potassium oxybate). GHB is also produced as a result of fermentation, and is found in small quantities in some beers and wines, beef and small citrus fruits.
More research is required to figure this all out, but given the close association between appetite and sleep regulation, it would not be surprising if MCH plays a part in sleep. Arousal and Sedation. Acetylcholine, dopamine, glutamate, histamine, norepinephrine, orexin, and serotonin are all active in promoting wakefulness. Some neurons (brain cells) specialize in releasing certain neurotransmitters and scientists have found the firing rates of those neurons can vary with wakefulness and sleep.
