BINAURAL INTERACTION IN LATERAL LEMNISCUS OF CAT

Abstract

Electrophysiological responses to auditory click stimuli were recorded in 8 cats. Statistically significant interaction was found when the time interval between paired clicks, one delivered to each ear, was less than 2 milliseconds. Previous results, indicating lack of interaction below the inferior colliculi, are discussed. The curve of degree of interaction at the lemniscus versus the time interval between paired clicks is similar to the curve for the first component of the response of the inferior colliculus.
