Based on previous studies, researchers have hypothesized that recreational noise exposure might damage the circuitry between
sensory hair cells in the inner ear and their auditory nerve targets that deliver information to the brain.
When the head accelerates or decelerates, they bend
the sensory hair cells and send a signal to the brain telling it which way is up.
In the inner ear of vertebrates, the balance system consists of three semicircular canals that contain fluid and
sensory hair cells that detect movement of the head.
«When
sensory hair cells in the ear die, they are not repopulated.
In the recessive deafness model, gene therapy with TMC1 restored the ability of

CIB2, which is short for calcium and integrin - binding protein 2, is essential for the structure of stereocilia, the structures at the top of
the sensory hair cells in the inner ear.
As a result,
the sensory hair cell bundles that receive sound and signal the brain deteriorate and become disorganized, leading to profound hearing loss.

Specialized
sensory neurons in the inner ear, called
hair cells, are responsible for the detection of sounds, and this information is transmitted to the auditory cortex via several intermediate structures.
The inner ear comprises the hearing organ or cochlea, together with the five balance organs (the saccule, utricle and three semicircular canals), which contain the
sensory cells, or
hair cells, that detect mechanical vibrations and convert them into electrical signals.
Studies of deafness often emphasize the role of
hair cells, the
sensory cells that transmit sound signals to the brain.

cells in the inner ear below
hair cells — known as supporting
cells — can become the
sensory cells themselves when stimulated by a protein that blocks Notch signaling, which is an important mechanism for
cell communication.

sensory cells sporting microscopic hairlike projections, and when these so - called
hair cells deep inside the inner ear are destroyed by illness or loud noise, they are gone forever.

hair cells, but if the
sensory neurons are damaged, hearing is still limited.

hair cells.
