Popis:	The interrelationship of cerebral hemodynamics and cerebral vascular tonus was studied in 36 patients with epilepsy during activation of discharges and provocation of epileptic seizures by hyperventilation and intravenous corazol infusion by simultaneous EEG and REG recording. It was found that regional functional hyperemia in the brain corresponding to the side of the epileptogenic focus increases during activation of the discharges despite a certain increase in the tonus of the cerebral vessels. During and immediately after an epileptic seizure angiospasm is replaced by vasodilation with further growth in blood filling of the brain. The possible mechanisms of the vascular reaction are discussed.
