WebThe primary auditory cortex (Fig. 6B; Brodmann area 41) is located along the upper bank of the superior temporal gyrus, within the lateral sulcus on two gyri known as Heschl's gyri. Similar to other sensory cortices, the primary auditory cortex is organized in columns, such that each column of cells responds maximally to an acoustic stimulus of ... WebCentral hearing loss is caused by a lesion in the central auditory pathway or in the auditory cortex. The auditory cortex processes and interprets the sounds amplified and received by the ossicles and cochlear hair cells. The auditory cortex is located on the transverse temporal gyri of Heschl.
