Response of binaural neurons of dog superior olivary complex to dichotic tonal stimuli: some physiological mechanisms of sound localization.

THE LOCALIZATION of high-frequency sinusoids depends on differences in the intensity of the sounds arriving at the two ears, that of low-frequency sinusoids on differences in phase (30). The present paper considers how the introduction of these two cues affects the discharge of individual binaural neurons of the superior olivary complex. Also described is the response of these cells to variations in the average intensity of binaural stimuli. Most of the neurons were located in the medial superior olive (MSO) or the medial preolivary nucleus (MPO).
