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. 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.

The effect of increased intracranial pressure (ICP) on arterial peripheral (PBP) and cerebral blood pressure (CBP) was studied in 16 rabbits (New Zealand White). Changes of arterial blood pressure in peripheral and cerebral blood circulation were caused by a temporary (3 min) ICP increase. A raised ICP was obtained by infusing into the left lateral brain ventricle artificial cerebrospinal fluid at a pressure equal to 50, 100, and 150% of the initial CBP value. The experiments carried out showed that on reaching the initial CBP value, increased ICP induced Cushing response. The magnitude and duration of this reaction changed with increasing ICP, the intensity of the changes depending on the brain region in which the ICP increase was initiated.
