Homeostatic systems are controlled by hypothalamic neurons that sense endogenous factors, including temperature, osmolality, glucose, and reproductive hormones. The concept of "functional specificity" implies that each neuron senses only one factor, but in vitro studies show that a neuron can respond to multiple factors. This may explain many interactions observed between regulatory systems.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
