| Popis: | In this paper, we compare some of the neural strategies forsound localization and encoding interaural time differences(ITDs) in three predatory species of Reptilia, alligators, barnowls and geckos. Birds and crocodilians are sister groupsamong the extant archosaurs, while geckos are lepidosaurs.Despite the similar organization of their auditory systems,archosaurs and lizards use different strategies for encodingthe ITDs that underlie localization of sound in azimuth. Barnowls encode ITD information using a place map, which iscomposed of neurons serving as labeled lines tuned for preferredspatial locations, while geckos may use a meter strategyor population code composed of broadly sensitive neuronsthat represent ITD via changes in the firing rate.
