Highlight: Chloride increases response to pheromones and odors in mouse sensory neurons
The vomeronasal organ (VNO) is an odor detection system that mediates many pheromone-sensitive behaviors. Vomeronasal sensory neurons (VSNs), located in the VNO, are the initial site of interaction with odors and pheromones. ...
