Response of Neurons of The Inferior Colliculi of Cats To Changes in the Intensity of One of The Monaural Components of Binaurally Presented Stimuli

In spite of the large quantity of psychophysiological investigations of binaural hearing, a systematic study of its concrete mechanisms has only been begun comparatively recently (cf. review [1]). In particular, changes in neuron response under conditions of lateral differentiation brought about by varying the intensity of one of the monaural components of binaurally presented stimuli have been studied in detail only at the site of the superior olivary body (3, 4, 6) — the first section of the auditory system — where afferent fibers from the right and left cochlea converge (7, 9). Published data provide evidence that variations in the intensity of one of the monaural components of binaurally presented signals has an appreciable effect on the firing rate of single neurons of the inferior colli cuius (5, 8), which is situated directly behind the superior olivary body of the auditory system. in the present report, the types of response of neurons in the inferior colliculus to variations in the intensity of one of the monaural components of binaurally presented stimuli are systematically investigated.
