Summary
We hypothesized that infusion of VIP may induce headache in healthy subjects and that VIP
induced headache may be associated with dilatation of intra- and extracerebral blood vessels.
To test this hypothesis, we performed a double blind placebo controlled crossover study in
normal human volunteers and studied the effect on headache and cerebral as well as
hemodynamic parameters.
