An in vivo rat model to study calcitonin gene related peptide release following activation of the trigeminal vascular system

Abstract
Calcitonin gene related peptide (CGRP) released from the C-fibers projecting from the trigeminal ganglion to the meninges has been suggested to play a crucial role in the pathophysiology of headache, particularly migraine. In humans it has been shown that CGRP is released during migraine-att
