Electrical stimulation on the hypothalamus in alert cats increases the blood pressure and inhibits the baroceptor reflexes. In animals with extirpated sinocarotid and aortic nerves the pressor reactions are perversed to depressor ones at threshold stimulation of the hypothalamus. Meanwhile suprathreshold stimulation of this organ leads to emergence of depressor-pressor responses. It is suggested that inhibition of the baroceptor reflexes is one of the mechanisms of the hypertensive reaction emergence at stimulation of the hypothalamus.
