Cortical deafness (verbal auditory agnosia) is associated with lesion location in which region?

Cortical deafness occurs when the primary auditory cortex is damaged in both hemispheres. The primary auditory cortex sits in the transverse temporal gyri, known as Heschl's gyrus, in each side of the brain. When both Heschl's gyri are impaired, auditory signals can no longer be consciously perceived, even though the ears and the lower auditory pathways are intact. If only one side is damaged, the other hemisphere can still process sounds, so complete deafness does not occur. Lesions in other areas, like the right frontal operculum or the superior temporal sulcus, disrupt different aspects of auditory processing but do not produce true cortical deafness.
