The reactivity of cerebral arteries have been examined in three groups of patients (young, middle and adult ages). The medium meanings of the blood flow velocity (V) and the pulsativity index (Pi) were registrated in MCA and PCA under hypercapnia, hyperventilation and light stimulation. It was revealed that the reactivity of cerebral arteries in middle and(More)
