Female mice apparently become as randy as males after their senses of smell are tampered with, ending up aggressively trying to mount any mouse that moves, research now reveals.
These findings open the question as to whether circuits for male behavior exist in a dormant state in females, and vice versa, in other species — including in humans.
In many animals, the vomeronasal organ often helps detect scents.
In mice, it especially helps detect pheromones, molecules used to attract the opposite sex and to communicate other signals linked with social behavior, such as parenting or aggression.
