The absence of orexin results in narcolepsy-cataplexy. While the function of the central orexinergic system in sleep regulation has been well studied, the role of orexin in motor control is largely unknown. Here, we show that orexin-A acts via OX1and OX2receptors to directly depolarize neurons in the rat lateral vestibular nucleus (LVN), a subcortical motor center, and enhance their sensitivity. A dual ionic mechanism involving both Na+-Ca2+exchangers and inward rectifier K+channels underlies these effects. Furthermore, orexin-A regulates central vestibular-mediated posture, motor balance and negative geotaxis. Orexin is critical when an animal is facing a major motor challenge as opposed to during rest and general movements. Therefore, orexin participates not only in sleep and emotion (nonsomatic) but also in motor (somatic) regulation, suggesting that the central orexinergic system plays an important role in somatic-nonsomatic integration. These findings may account for why the absence of orexin results in narcolepsy-cataplexy.
