Pheromone

A pheromone is a chemical substance that is secreted or excreted by an organism into the environment, which evokes physiological and/or social responses in one or more organisms of the same species. Perception of these chemical signals may be by olfaction or by contact.

    Olfactory experience can alter the relative abundance of neurons expressing specific chemoreceptors. Here, the authors demonstrate that the distinct odor experiences of sex-separated male and female mice induce sex-specific differences in the abundance of neurons that detect sexually dimorphic odors.

    Sex pheromones that increase mating have been reported across a number of different species, yet there is little known about pheromones that suppress female mating drive. This study reports that juvenile female mice release a pheromone, ESP22, which suppresses sexual receptivity of adult female mice by evoking a robust rejection behavior upon male mounting.

    Mate preference and copulatory behavior in female rodents are coordinated with the ovulation cycles of the animal. This study shows that hypothalamic kisspeptin neurons control both mate choice and copulation, and therefore, that sexual behavior and ovulation may be synchronized by the same neuropeptide.

    Social behaviors require neural circuits to process social cues and orchestrate motivational states. This study identifies a subpopulation of hypothalamic neurons expressing neurotensin that are engaged by social and hormonal signals. These neurons project to midbrain dopaminergic reward systems to promote and reinforce social and motivated behavior in a hormone-sensitive manner.

    Male pheromones cis-vaccenyl acetate (cVA) and (Z)-7-Tricosene (7-T) mediate chemical mate-guarding in female D. melanogaster. Here, Laturney and Billeter show that females actively eject cVA from their reproductive tract post-copulation, and that cVA in concert with 7-T can reduce female attractiveness post-mating.
