title: [Role of the caudate nucleus in differentiating spatially separated acoustic signals in the dog].
abstract: In tests on dogs the influence has been studied of bilateral electrolytic lesion of the caudate nuclei heads on realization of acquired conditioned instrumental defensive reactions to spatially separated sound signals (clicks series) under dichotic stimulation. It is shown that caudatectomy does not influence the dogs differentiation of the side of monaural sound stimulation, but leads to their absolute disability for a long time to differentiate right- and left-side positions of the sound image, modelled by changes in interaural difference in time of sound signal arrival at binaural stimulation.
