Abstract
Mayer waves and undulating ventricular waves were produced in hydrocephalic and nonhydrocephalic animals. Carotid sinus stimulation resulted in an increase in both wave forms, whereas carotid sinus denervation resulted in their diminution. The reflex pathway involved in the production of the waves constitutes a feedback mechanism between carotid sinus, the peripheral proprioceptor, and medullary vasomotor center. The ventricular fluid pressure wave forms are the intracranial manifestations of passively transmitted changes occurring in the systemic circulation secondary to dysfunction of the brain stem.
