Arm Description
12 healthy volunteers will receive PACAP27 (10 picomole/kg/min) over 20 min
6 healthy volunteers will receive placebo (Saline) over 20 min
Outcomes
Primary Outcome Measures
Dilation of extra- and intracerebral arteries
A single-slab 3D time-of-flight (3D TOF) MRA of extra- and intracranial arteries will be acquired as described in previous studies (Amin et al., 2013, 2014). MRA data will be analyzed by LKEB-MRA vessel wall analysis software program. We will measure the circumference of vessels in millimeter in five predefined time points (0, 20, 110, 200 and 290 min)
Secondary Outcome Measures
Headache
Headache intensity (Visual analog scale 0-10), characteristics, location and migraine associated symptoms will be recorded in questionnaire at hospital (6 hours) and post hospital (18 hours). In hospital phase, headache questionnaire will be filled every 30 min and post hospital every hour.

5. Study Description
Brief Summary
Studying Pituitary adenylate cyclase-activating peptide 27 (PACAP27) effects on extra- and intracerebral arteries assessed by MRA on healthy volunteers.
Detailed Description
PACAP neuropeptide, which belongs to the vasoactive intestinal polypeptide (VIP)/glucagon/secretin family. PACAP exists in two forms: Studying Pituitary adenylate cyclase-activating peptide 38 (PACAP38), which consists of 38 amino acids and PACAP27 which contains 27 amino acids at its N-terminus. PACAP38 is implicated in migraine pathophysiology however PACAP27 is not studied well. Therefore, the investigators will study PACAP27's effect on extra- and intracerebral arteries assessed by MRA on healthy volunteers.
