Orexin - Interaction With Other Neurotransmitter Systems
... Orexinergic neurons have been shown to be sensitive to inputs from Group III metabotropic glutamate receptors, adenosine A1 receptors, muscarinic M3 receptors, serotonin 5-HT1A receptors, neuropeptide Y ... Orexinergic neurons themselves regulate release of acetylcholine, serotonin and noradrenaline, so despite the relatively small number of orexinergic neurons compared to other neurotransmitter systems in the brain ...
