| The scientists also found that the orexin neurons in the brains of injured mice were much less active than the same neurons in uninjured mice. |
| Belsomra is an orexin receptor antagonist and is the first approved drug of this type. |
| For example, physical activity increased in rats when injected with orexin, a brain chemical associated with sexual arousal. |
| Shin-ichiro Imai demonstrated that the protein sirtuin is required in order for calorie restriction to enhance the activity of orexin. |
| Orexin neurons are exclusively localized in the lateral hypothalamic area and project their fibers to the entire central nervous system. |
| Instead, opt for lean proteins like fish, which are less sensitive to orexin, a hormone that keeps you awake. |
