Hearing and brain structure
WebStructure of the inner ear The inner ear is located near the middle ear, and under the temporal bone of the brain that protects structures and nerves of the ear. The inner ear consists of two different labyrinths or networks of passages, the membranous labyrinth, and the bony labyrinth. The first labyrinth is contained within the latter. As with other primary sensory cortical areas, auditory sensations reach perception only if received and processed by a cortical area. Evidence for this comes from lesion studies in human patients who have sustained damage to cortical areas through tumors or strokes, or from animal experiments in which cortical areas were deactivated by surgical lesions or other methods. Damage to the auditory cortex in humans leads to a loss of any awareness of sound, but an abilit…
