Abstract.

The mammalian olfactory system has evolved complex mechanisms to detect a vast range of molecular cues. In rodents, the olfactory system comprises several distinct subsystems. Current interest has focused on the exact role that each of these subsystems plays in detecting molecular information and regulating chemosensorydependent behaviors. Here, we summarize recent results showing that the mouse main and accessory olfactory systems detect, at least in part, overlapping sets of social chemosignals. These findings give rise to a model that involves parallel processing of the same molecular cues in both systems. Together with previous work, this model will lead to a better understanding of the general organization of chemical communication in mammals and give a new direction for future experiments.
