Summary: The study sought to determine the role of noradrenergic neurons in hypertonic saline infusion (HSI)-induced hemodynamic recovery. Findings show that together the A1 and A2 neurons are essential to HSI-induced cardiovascular recovery in hypovolemia.

Usage: Medullary catecholaminergic neurons were lesioned by nanoinjection of Anti-DBH-SAP (0.105 ng·nl−1) into A1, A2, or both (LES A1; LES A2; or LES A1+A2, respectively). Sham rats received nanoinjections of unconjugated saporin in the same regions.
