Sensory neurobiology: demystifying the sick sense

Curr Biol. 2015 Feb 16;25(4):R153-5. doi: 10.1016/j.cub.2015.01.003.


The vomeronasal organ, a sensory structure within the olfactory system, detects chemical signals that affect social and sexual behaviors and that elicit responses to predator odors. A recent study demonstrates that innate avoidance of sick conspecifics requires an intact vomeronasal organ, expanding the repertoire of biological functions known to be mediated by this olfactory subsystem.
