Among mice, pheromones and other social odor cues convey information about sex, social status, and identity; however, the molecular nature of these cues is essentially unknown. To identify these cues, we screened chromatographic fractions of female mouse urine for their ability to cause reproducible firing rate increases in the pheromone-detecting(More)
Male mice secrete exocrine-gland-secreting peptide 1 (ESP1) from the extraorbital lacrimal gland into tear fluid [1]. Other mice detect ESP1 through sensory neurons in the vomeronasal organ (VNO), a secondary olfactory system that senses pheromonal information, including sex, strain, and species. ESP1 is now known to be a member of a multigene family that(More)
