A change in the arterial pressure-sympathetic activity or heart rate relation (baroreflex
resetting) can result from resetting of baroreceptors ('peripheral'resetting) or from an altered …

SUMMARY 1 Rapid resetting of the arterial baroreceptor threshold in the normal circulation
extends the pressure range over which baroreflexes operate at high gain. During sustained …

1. Pressure threshold (Pth) and suprathreshold pressure sensitivity (Sth) are important
measures of the pressure-discharge characteristics of arterial baroreceptors. An in vitro …

SUMMARY 1 The arterial baroreceptors are reset to operate at higher pressure levels in
hypertension. Rapid (acute) resetting occurs within the first few minutes after elevation of …

The threshold pressure of single baroreceptor units is decreased after compared with before
exposure to pulsatile pressure according to previous studies in our laboratory. The purpose …

We studied human baroreflex resetting during 25 min of drug-induced arterial pressure
changes in 10 healthy volunteers. Average (+/-SE) base-line systolic pressure of 113+/-4 fell …

Interaction among action potential trains was examined in electroneurograms (ENGs) from
filaments containing several fibers. In an in vitro preparation, increasing aortic pressure …

Isosmotic decreases in central venous pressure do not stimulate arginine vasopressin (AVP)
secretion in normal humans, while symptomatic vasovagal hypotension produces large rises …

1. Acute baroreflex resetting in the control of arterial pressure was studied in six chronically
instrumented, conscious dogs. Following aortic baroreceptor denervation, the carotid …

The tachycardia elicited by decreases in aortic pressure produced by various calcium
antagonists, regardless of their chemical structures, is not always simply related to the …
