orexins are highly excitatory neuropeptides that were first discovered in the brains of rats. it is a peptide that is produced by a very small population of cells in the lateral and posterior hypothalamus. orexins strongly excite various brain nuclei (neurons) to affect an organism’s wakefulness by affecting their dopamine, norepinephrine, histamine and acetylcholine systems. these systems work together to stabilize the organism’s sleep cycles. once made, the orexin peptides can bind to the orexin receptor; which is a g protein coupled receptor. this g protein linked receptor senses molecules outside the cell and activates inside signal transduction pathways to elicit cellular responses.
