Dopaminergic Neurons Controlling Anterior Pituitary Functions: Anatomy and Ontogenesis in Zebrafish.

abstract：:The control of ACTH secretion by opiates seems to involve stimulatory and inhibitory pathways, since opiate agonists and antagonists are capable of releasing ACTH in conscious rats. To elucidate the role of different opiate receptors in the control of ACTH release, rats were treated with receptor-selective opiate agon...
