where is the auditory cortex located in the brain
Auditory cortex It is located bilaterally, roughly at the upper sides of the temporal lobes â€“ in humans on the superior temporal plane, within the lateral fissure and comprising parts of Heschl's gyrus and the superior temporal gyrus, including planum polare and planum temporale (roughly Brodmann areas 41, 42, and partially 22).[2] Unilateral destruction results in slight hearing loss, whereas bilateral destruction results in cortical deafness.
Organ of Corti The organ of Corti is located in the cochlea of the inner ear between the vestibular duct and the tympanic duct and is composed of mechanosensory cells, known as hair cells.[2] Strategically positioned on the basilar membrane of the organ of Corti are three rows of outer hair cells (OHCs) and one row of inner hair cells (IHCs).[4] Separating these hair cells are supporting cells: Deiters cells, also called phalangeal cells, which separate and support both the OHCs and the IHCs.[4]
