Distributions of the following neuropeptides were studied by means of the unlabeled peroxidase-antiperoxidase complex (PAP)method and the double PAP method in the brain and hypophysis of the hagfish (Eptatretus burgeri): somatostatin (SRIF), arginine vasotocin (AVT), neurophysin I and II, thyrotrophin releasing hormone (TRH), substance P, neurotensin, α-endorphin, and β-endorphin. SRIF-immunoreactive perikarya were located in the nucleus postopticus and nucleus hypothalamicus. However, SRIF-immunoreactive fibers and terminals were not detected in the hypothalamo-hypophysial region. AVT-immunoreactive perikarya were distributed in the nucleus postopticus and projected most fibers to the neural lobe and few to the median eminence. These two neuropeptides were not detected in the adenohypophysis. Other neuropeptides examined were not demonstrated in eigher the hypothalamus or the hypophysis.
