Abstract
The effect of vasoactive intestinal polypeptide (VIP) on the cerebral blood flow was investigated in the goat. An electromagnetic flow probe was placed around the internal maxillary artery for continuous measurement of ipsilateral blood flow. Intraarterial injection of VIP resulted in a dose‐dependent increase in the cerebral blood flow. The effect was not antagonized by any of the antagonists atropine, propranolol, phentolamine and naloxone administered intraarterially 1 min before VIP. It is discussed that VIP may play a physiological role in the local blood flow regulation in the CNS.Keywords
