Abstract

Comparison of neuronal responses (118 units) in the inferior colliculus of anesthetized rats to frequency-modulated (FM) sounds and time characteristics of two-tone inhibition were carried out. High sensitivity to certain direction of FM in 2/3 of neurons coincide with spatial characteristics of excitatory and nihibitory areas: their shape, width and arrangement. In 1/3 of neurons directional response specificity is shown to be determined by different time course of inhibitory process evoked by high-frequency and low-frequency tones.
