In 1849, when Arnold Berthold noticed castrated cockerels behaved differently, and replacement of their testes into a body cavity restored their normal behavior, the world of behavioral and comparative neuroendocrinology blossomed. We have truly learned volumes about how secreted signals can affect the brain and an impressive range of behaviors. Along the way we have noticed that hormones can also work quickly, in manners tantalizing and inconsistent with our appreciation of neuroendocrine processes. Thus, an enormous gap in our understanding lies not in which hormones mediate specific behaviors, but how mechanisms of hormone provision and response modulate rapid changes in neurophysiology including behavior. This symposium will focus on the study of rapid neuroendocrine function in various taxa and behaviors, uniting scientists who study a broad array of systems and use different, advanced techniques, to study neural changes that influence behaviors. Further, this symposium will take a very integrative approach to what “rapid” neuroendocrine function means, with a unified theme of embarking on new frontiers – what have we learned, where should we go next, how, and why? Because of this, all speakers will contribute a significant amount of their talks to where the field is heading and how their work and emerging technologies will help take us there. Understanding how neuromechanisms can alter the function of specific brain areas as well as the flow of information among areas of the brain will shed light on downstream consequences for sensorimotor integration, behavior, and ultimately evolution.
