Origin of fibers innervating the basilar artery of the cat

摘要: The afferent and efferent projections of the cat basilar artery were examined using retrograde axoplasmic transport techniques. Following application horseradish peroxidase (HRP) or wheat germ agglutinin-HRP (WGA-HRP) to vessel wall, retrogradely labeled cells observed in trigeminal, superior vagal, cervical, stellate pterygopalatine ganglia. WGA-HRP injected into ganglion was transported reticular formation previously described as salivatory nucleus. These results are discussed relation recent physiological data demonstrating neural involvement control cerebral blood flow vascular headache.
