How is a pheromone detected?

Pheromones are detected through specialized sensory receptors located in the vomeronasal organ (VNO), which is part of the olfactory system. When pheromones are released into the environment, they bind to these receptors, triggering neural signals that are transmitted to the brain. This process allows organisms to perceive chemical signals related to social interactions, mating, and territory marking. In some species, pheromone detection can also occur through the main olfactory system, enhancing their ability to respond to these chemical cues.
