[Different sensitivities of cerebral arterial systems to noradrenaline].
The tests carried out on the nonanesthetized and anesthetized cats showed noradrenaline to exert a direct influence on the cerebral vessels, increasing their tone. The drug produced different effect on the vessels of different arterial systems of the brain. Noradrenaline increased the resistance of the carotid arteries to a greater degree than in the vertebral arterial system.
