| Outline of Final Research Achievements |
Pheromones have powerful effects on animals, inducing specific behaviors or physiological changes to the recipient through brain function. In mammals, pheromones that regulate physiology have yet to be identified conclusively, and their mechanism of action is almost completely unknown. In this study, we identified a volatile molecule, 4-ethyloctanal, as a “male effect” pheromone that activates the central regulator of reproduction in female goats, and a mixture of 4-methylpentanal and hexanal as an alarm pheromone that increases anxiety in other rats. We also found that 4-methylpentanal and hexanal might be detected via the vomeronasal system and via the main olfactory system, respectively.
