International Society for Autonomic Neuroscience (ISAN) is a society comprising of researchers, medical professionals, academics, industry professionals and students working with the autonomic nervous system.

The purpose of ISAN is to facilitate communication between those working in this area of neuroscience and to raise the profile of autonomic neuroscience. It will arrange meetings, lobby for an improved representation of autonomic neuroscience in such organizations as IBRO, and aid communication between scientists who work on all aspects of the autonomic nervous system.
