Discharge characteristics and rapid resetting of autoactive aortic baroreceptors in rats.

Abstract

1. An in vitro aortic arch-aortic nerve preparation was used to characterize the pressure-discharge properties of aortic 'autoactive' baroreceptors (aBRs), a functionally unique group of baroreceptors that discharge continuously below pressure threshold (Pth). These units contrast to more familiar 'quiescent' BRs (qBRs) that are silent below Pth. This study… (More)
