Preliminary Analysis of the Neurogenic Vasoconstriction of Basilar Artery
A neurogenic contraction of the caudal segment of the rabbit basilar artery has been demonstrated (Fig. 1), which is comparable in magnitude to that in other systemic vessels (1). Adjacent parts of the vertebral and the cephalic three-quarters of the basilar arteries were relatively unresponsive. At 10 cps, for example, the mean developed force in the caudal segment was almost 10 times that in the cephalic.
