In this second article of a three-part series, the auditory areas of the cerebrum are defined. Anatomical descriptions of various structures within the auditory areas of the brain as well as an overview of selected electrophysiological research on auditory cortex are presented. Ablation studies involving auditory cortex and principal aspects of the vascular neuroanatomy are also reviewed. Finally, extensive clinical findings are presented from a case with damage to the cerebral auditory areas.
