Effects of cochlear lesions on the threshold responses of the auditory cortex in chronic experiments.

Abstract

Cortical potentials were recorded in cats'' auditory cortex following the production of restricted cochlear lesions. "The findings support the previous concepts of an orderly frequency distribution within the cochlea, high frequencies at the basal end and low frequencies at the apex." Results of this study compare well with previous determinations of auditory thresholds by conditioned response techniques following cochlear damage.
