Neural Mechanisms That Underlie Angina-Induced Referred Pain in the Trigeminal Nerve Territory: A c-Fos Study in Rats

<table>Effects of the lesion of the C1-C2 spinal segments on c-Fos expression in vehicle-infused (a) and PPS-infused (b) rats. Photomicrographs show c-Fos expression in the left Sp5C. Fos-labeled cells were observed in the intact rats (a-A and b-A). The number of Fos-labeled cells remarkably increased in the lesioned rats (a-B and b-B) compared with the intact rats.</table>
