The auditory cortex is the most highly organized processing unit of sound in the brain. This cortex area is the neural crux of hearing, and—in humans—language and music. The auditory cortex is divided into three separate parts: the primary, secondary, and tertiary auditory cortex.
Within the primary auditory cortex, the auditosensory cortex extends posteromedially over the gyrus. [2] Brodmann area 42 is an auditory core region bordered medially by Brodmann area 41 and laterally by Brodmann area 22. [2] The auditosensory cortex demarcates the lateral edge of Brodmann area 41.

Vision: The visual area known as V1, striate cortex, or (primary visual cortex, Brodmann area 17) is located on the calcarine sulcus deep within the inside folds of the occipital lobe. Hearing: The primary auditory cortex is located on the transverse gyri that lie on the back of the superior temporal convolution of the temporal lobes.
The cochlear nerve (also auditory nerve or acoustic nerve) is one of two parts of the vestibulocochlear nerve, a cranial nerve present in amniotes, the other part being the vestibular nerve. The cochlear nerve carries auditory sensory information from the cochlea of the inner ear directly to the brain .
This area is called the helicotrema. This continuation at the helicotrema allows fluid being pushed into the vestibular duct by the oval window to move back out via movement in the tympanic duct and deflection of the round window; since the fluid is nearly incompressible and the bony walls are rigid, it is essential for the conserved fluid ...
The hair cells are the primary auditory receptor cells and they are also known as auditory sensory cells, acoustic hair cells, auditory cells or cells of Corti. The organ of Corti is lined with a single row of inner hair cells and three rows of outer hair cells. The hair cells have a hair bundle at the apical surface of the cell.
The auditory system is the sensory system for the sense of hearing. ... VLPO have the same function as DPO, but act in a different area. PVO, CPO, RPO, VMPO, ALPO and ...
The medial geniculate nucleus (MGN) or medial geniculate body (MGB) is part of the auditory thalamus and represents the thalamic relay between the inferior colliculus (IC) and the auditory cortex (AC). [1]
