Sound Localization and Pinna Movements in the Behaving Cat

  • Tom C. T. Yin

The ability to localize the source of a sound is an important function of the auditory system. It is of obvious utility for both prey and predator, as well as for social reasons, to quickly and accurately identify the locus of a sound source. Consequently, the neural mechanisms underlying sound localization have been of much interest to psychophysi- cists, anatomists and physiologists studying the auditory system. It is probably safe to say that we understand more about the central processing of sound localization cues than of any other auditory function (e.g. pitch perception, vowel discrimination)(see Irvine, 1986; Yinetal. 1997).
