Glucose is the primary fuel for the vast majority of cells, and animals have evolved essential
cellular, autonomic, endocrine, and behavioral measures to counteract both hypo-and
hyperglycemia. A central component of these counterregulatory mechanisms is the ability of
specific sensory elements to detect changes in blood glucose and then use that information
to produce appropriate counterregulatory responses. Here we focus on the organization of
the neural systems that are engaged by glucosensing mechanisms when blood glucose …
