abstract：:The vomeronasal organ (VNO) is a chemoreceptive organ that is thought to transduce pheromones into electrical responses that regulate sexual, hormonal and reproductive function in mammals. The characteristics of pheromone signal detection by vomeronasal neurons remain unclear. Here we use a mouse VNO slice preparation...
