Abstract
1Severe auditory deficit due to bilateral lesions of the primary auditory cortex or auditory radiation is rare. This serious hearing problem is called “auditory agnosia” or “cortical deafness.” Most studies on humans are single or double case reports (1–6) and have led us to question whether bilateral lesions in the human primary auditory cortex can cause complete deafness. However, in animal experiments, Neff et al. (7) noted that bilateral ablation of the primary auditory cortex does not cause permanent deafness, with preservation of pure-tone thresholds.
This section of the chapter was excerpted from: Kaga K, Shindo M, Tanaka Y. Central auditory information processing in patients with bilateral auditory cortex lesions. Acta Otolaryngol Suppl (Stockh) 532:77–82, 1997.
