[Character of baroreceptor reflexes during emotional stress in awake animals]

The baroreflectory bradycardia in the cat was inhibited during emotional tension leading to hypertensive reaction. The emotional tension caused a hypotensive reaction after extirpation of sino-carotid and aortic nerves. After recovery of the baroreceptor reflexes, the amplitude and duration of this reaction decreased and hypertensive reaction followed. One of the mechanisms of the hypertension during emotional stress seems to involve the inhibition of the baroreceptor reflexes.
