The discovery of a peptide that is secreted from the eyes of male mice and elicits neuronal activity in the vomeronasal organ (VNO) of females, points to a new mode of chemical communication between mammals, according to the authors of a new study in Nature. As well as identifying a novel source of mammalian chemical signals, the study suggests that such signals can be mediated by non-volatile molecules transferred during direct contact between individuals.
