The vomeronasal organ VNO is important for activating accessory olfactory pathways that are involved in sexually dimorphic mating behavior. The VNO of male garter snakes is critically important for detection of, and response to, female sex pheromones.

The amplitude of the inward current was dose dependent, and the relationship could be fitted by the Hill equation.
