Diet exerts a major impact on health and aging. The nervous system plays an important role in this process but, thus far, how food signals are interpreted by the nervous system has been a mystery. A new study has found that serotonin and TGF-beta hormone levels in specific neurons of C. elegans communicate information about food abundance in roundworms. These signals from the nervous system influence the animal’s lifespan, thus mediating the effects of food on aging.
