In page Auditory agnosia:

"

In 1885,[4] Lichtheim also reported of an auditory agnosia patient. This patient, in addition to word deafness, was impaired at recognizing environmental sounds and melodies. Based on this case study, as well as other aphasic patients, Lichtheim proposed that the language reception center receives afferents from upstream auditory and visual word recognition centers, and that damage to these regions results in word deafness or word blindness (i.e., alexia), respectively. Because the lesion of Lichtheim's auditory agnosia patient was sub-cortical deep to the posterior STG (superior temporal gyrus), Lichtheim renamed auditory agnosia as "sub-cortical speech deafness".[citation needed]
