Melatonin acts through MT1 and MT2 receptors to suppress firing of SCN neurons, thereby disinhibiting the sleep-promoting neurons in the VLPO. Melatonin also suppresses excitatory signals from SCN to lateral HTH which secretes orexin (hypocretin) which acts on OX1 and OX2 receptors to activate monoamine arousal systems.
