“…The closedloop gain was calculated as: Pdfrf/P1err. The open-loop gain corresponds to -G/(l -G0) (Scher, O'Leary & Sheriff, 1991).…”

“…In the present study, the lower NE concentrations in the HYPO group, coupled with marked differences in HR and AP, confirms that inadequate sympathetic outflow may be responsible for orthostatic intolerance in healthy elderly men. It is well documented that the arterial baroreceptors provide the critical regulation of AP during orthostatic stress [4], and that the unloading of arterial baroreceptors results in reflex increases in sympathetic outflow and decreases in parasympathetic activity [29]. Significant reductions in AP and PP, coupled with increases in HR have been suggested as evidence of arterial baroreceptor activation [30].…”

“…Distension of the vessels send an increasing frequency of action potentials to the Nucleus Tractus Solitarii (NTS) via CN IX, signaling an increase in mean arterial BP; alternatively, a decrease in BP decreases receptor activity until it stops altogether around 40 to 60 mmHg. Firing frequency is further increased by rapid increases in BP: twice as many action potentials are generated by an increasing pressure of 150 mmHg than a stationary pressure of 150 mmHg (Hall 2011, Scher et al 1991. The NTS responds to an increase in BP by inhibiting descending sympathetic efferents and exciting vagal efferents, causing both a decrease in HR and arterial vasoconstriction.…”

“…BRS, also called "BRS gain," of significant sequences is measured by quantifying the change of RRI in response to changes in SBP to get the slope in ms/mmHg (Sagawa 2011). Despite the name, BRS slope does not reflect baroreceptor activity alone, but rather the integration of various reflex arcs that alter HR and vasoconstriction to maintain BP (including cardiopulmonary reflexes, baroreceptor reflexes, and the low-pressure receptors) (Scher et al 1991). Isolation of baroreceptor reflex activity requires either electrical or physical perturbation of the baroreceptors, a Valsalva maneuver, or pharmacological intervention (Hart et al 2010, Kamiya et al 2011, Vogel et al 2005.…”
