Both smells and pheromones may arouse instinctive behaviors in mammals

Researchers have found that both smells and pheromones can arouse instinctive behaviors in mammals, including humans. This is achieved through the detection of odorants by the vomeronasal organ (VNO) and the olfactory epithelium (OE), with pheromone signals directly influencing mid-brain areas controlling behavior and hormonal responses.
