Identifying vagal sensory neurons driving the Bezold-Jarisch reflex

Abstract

Homeostatic reflexes are crucial for life, but the subpopulations of sensory neurons that stimulate these reflexes are largely unknown. A recent paper from Lovelace, Ma, and colleagues identified a population of sensory neurons in the cardiac ventricle that underlies the Bezold-Jarisch reflex and triggers syncope (fainting).
