[Inhibitory processes in neuronal reactions of the auditory cortex in the cat undergoing dichotic stimulation].

In experiments on anaesthetized cats, studies have been made of intracellular and extracellular responses of single units in the auditory cortex during dichotic stimulation simulating sound source motion. Responses of some cortical units exhibit strong dependence on the signal parameters related to spatial and directional characteristics of simulated sound source motion. Profound inhibition was invariably revealed at the beginning of sonic stimulation as well as during certain moments of its movement. The role of inhibition in formation of cortical reactions to sound source motion is discussed.
