Linear model of the baroreflex. Arterial pressure inputs relay through an element representing a constant gain with respect to the set point with a time delay imposed upon the circuit. The resonant frequency represents the frequency at which the phase angle falls to zero. The baroreceptor emergently generates corrective modulation of dynamic arterial pressure magnitude according to baroreflex- and crossmodally-modulated sympathetic and parasympathetic discharge.
