Reorganization of auditory cortex after neonatal high frequency cochlear hearing loss.

Author information

  • 1Hospital for Sick Children Research Institute, Toronto, Canada.

Abstract

Cochleotopic representation in cortex (AI) is extensively reorganized in cats having neonatal, bilateral high frequency cochlear hearing loss. Anterior areas of AI, normally devoted to high frequencies, contain neurons which are almost all tuned to one lower frequency. This frequency corresponds, at the level of the cochlea, to the border between normal and damaged haircell regions.
