Abstract

One of the fundamental features of hearing is the ability to localizethe sources of sounds, particularly brief sounds, which may warn of nearby animals. Yet not all mammals localize sound equally well with threshold acuity ranging from about 1 degrees for elephants and humans to mure than 25 degrees for gerbils and horses and a near absence of localization in some subterranean species. During the past decade evidence has accumulated that this variation cannot be accounted for simply by the availability of the physical cues for locus, Nor does it appearto be a function of an animal's lifestyle. Rather should-localizationacuity in mammals appears to be a function of the precision required of the visual orienting response to sound. Thus the neural integrationof hearing and vision in cortex, as well as in multimodal subcorticalstructures. is a reflection of their behavioral integration and evolutionary coupling.
