title: Vasoactive intestinal polypeptide (VIP) in the medulla oblongata of the guinea pig.
abstract: Using the peroxidase-antiperoxidase (PAP) technique brains of colchicine-treated guinea pigs were investigated for the occurrence of vasoactive intestinal polypeptide-like immunoreactive (VIP-IR) neurons. VIP-IR perikarya were found not only in previously documented areas of the cortex, hypothalamus and substantia grisea centralis, but also in the nucleus nervi vagi, nucleus solitarius and the formatio reticularis.
