We investigated whether a monosynaptic connection from the nucleus tractus solitarius (NTS) or the depressor ventrolateral medulla (VLM) to the pressor region of the rostral VLM (RVLM) constituted part of the reflex pathway activated by cardiopulmonary baroreceptors. Volume expansion in the conscious rabbit, which elicits renal nerve inhibition predominantly via cardiac mechanoreceptors, was us...
