TONIC INFLUENCE OF ROSTRAL BRAIN STRUCTURES ON PRESSURE REGULATORY MECHANISMS IN THE CAT.
Transection of vagi and carotid sinus nerves in anesthetized cats results in a rise of blood pressure and subsequent decerebration results in a fall. Decerebration alone results in a slight drop in blood pressure unchanged by subsequent nerve section. Rostral brain structures principally influence tonically brainstem mechanisms subserving baroreceptor reflex excitability rather than those maintaining normal blood pressure.
