Enhancement of conditioned arterial pressure responses in cats after brainstem lesions

MA Nathan, LW Tucker, WH Serverini, and DJ Reis

Cats were classically conditioned after the baroreceptor reflexes were abolished by bilateral placement of electrolytic lesions in the nucleus tractus solitarii. The conditioned increases in arterial pressure were more than five times larger than the responses obtained in similarly trained controls. This finding suggests that the baroreceptor reflexes actively inhibit conditioned increases of arterial pressure.
