Social Modulation of Associative Fear Learning by Pheromone Communication
Bredy, Timothy W.; Barad, Mark
Learning & Memory, v16 n1 p12-18 Jan 2009
Mice communicate through visual, vocal, and olfactory cues that influence innate, nonassociative behavior. We here report that exposure to a recently fear-conditioned familiar mouse impairs acquisition of conditioned fear and facilitates fear extinction, effects mimicked by both an olfactory chemosignal emitted by a recently fear-conditioned familiar mouse and by the putative stress-related anxiogenic pheromone [beta]-phenylethylamine ([beta]-PEA). Together, these findings suggest social modulation of higher-order cognitive processing through pheromone communication and support the concurrent excitor hypothesis of extinction learning.
