[Spatial characteristics of the reaction of the inferior colliculi in the cat to movement of the sound source].
The EP-series response of the inferior colliculus to clicks simulating sound source motion, reflects characteristics of this "motion" ("the motion effect", ME). ME distribution over the inferior colliculus practically coincided with the spatial distribution in cases when contralateral stimulation was more effective than the ipsilateral one. The spatial distribution in cases with no ME was identical with the distribution of cases of equal effectiveness of the contra and ipsilateral stimulations. The ME was shown to be connected with the binaural inhibitory effects and might probably be related to the activity of two main neuronal groups (the principal and multipolar ones).
