This chapter examines patterns of cerebral blood flow that develop in animals after unilateral trigeminal ganglionectomy. For this study blood flow was measured during acute severe hypertension (above 180 mmHg), and seizures. The latter two conditions are often associated with headache. From the information described in this chapter, significant asymmetries were anticipated in blood flow between the two sides, which would reflect the loss of a mechanism for cerebrovascular vasodilatation.

Keywords: vasomotor function; trigeminovascular fibres; lesion studies; cerebral blood flow; ganglionectomy; hypertension
