Chemical Communication in the Guinea Pig: Urinary Components of Low Volatility and Their Access to the Vomeronasal Organ
Abstract
Guinea pigs (Cavia sp.) utilize chemical information from conspecifics in the regulation of social behavior (Beauchamp et al., 1977; King, 1956; Rood, 1972), We have been Investigating a number of aspects of this communication system. Here, we will present observations and evidence from behavioral and chemical studies that suggest that information transfer among individuals is mediated at least in part by compounds of low volatility. If compounds of low volatility are used, the receptor organ(s) and the means by which the compounds reach the organ(s) are called into question. Volatile compounds can easily reach the olfactory receptor cells during inspiration; non-volatile substances presumably must reach appropriate receptors by some other means. We have hypothesized that the vomeronasal organ is involved in responses to chemical signals, particularly those of low volatility. We also will describe studies investigating access of non-volatile material to the vomeronasal organ.
