The effect of electrical stimulation of A and C fibres of the aortic nerves on arterial peripheral (PBP) and cerebral blood pressure (CBP) was studied in 12 rabbits (New Zealand White). The experiments have shown that selective stimulation of fibres A of the aortic nerves evokes every time depression of the arterial blood pressure in the peripheral circulation and slightly modifies pressure in the cerebral circulation. Selective stimulation of fibres C of the aortic nerves always elicits a significant decrease in arterial blood pressure in the peripheral circulation, whereas in the cerebral circulation it elicits a small decrease or a slight increase in arterial pressure. The obtained results point to a predominating role in depressor reaction of impulsation reaching the aortic arch through amyelic fibres C.<R> The depressor reaction in the peripheral circulation is highest with simultaneous stimulation of the right and left aortic nerve during stimulation of both fibre A and C.
