In a resting typical person, there is Mean Arterial Pressure (MAP) being detected by the baroreceptors. The baroreceptors have a resting frequency of afferent action potentials to the brainstem nuclei: parasympathetic CI, sympathetic CA and VM. At rest, the baroreceptors ensure that parasympathetic CI is ON, sympathetic CA is OFF, and sympathetic VM has only partial influence on blood vessels. If a drug blocked the production of baroreceptor afferent action potentials in a resting typical person, what effect would there be relative to baseline activity?
