Aminoglycosides can be toxic to
hair cells in many species (Brignull et al., 2009), but this has not yet been tested in cephalopods.
In hearing, sound travels into the ear and vibrates through various passageways, eventually rippling across the inner ear's
hair cells, sending electrical impulses that the brain recognizes as sound.
Washington, Feb 21 ( ANI ): For years, scientists have thought that the sound-sensing
hair cells in the inner ear cannot be replaced once they're lost.
A normal otoacoustic emission reading is a sign that the outer
hair cells are working no Fia.
Founded in 2009 with the goal to provide complete nonsurgical oxygen treatments and skin products, DermaOxy oxygen treatments involve pressing oxygen deep under the skin to revitalize deep layers of skin and
hair cells. Treatment instruments include airbrushes and the "in2OXY" pen.
The approach yielded clear images of the
hair cells, tiny structures that detect sound vibrations.
giant Pfizer is arguably the most advanced of the big players, with a drug in initial Phase I clinical testing trial for age-related sensorineural hearing loss that looks to enhance the function of existing
hair cells.
Finally,
hair cells in the fluid-filled inner air convert the vibrations into electrical nerve messages that are sent to the brain.
When
hair cells in the ear detect this they send a message to the brain.
To understand what is going on in the ear related to NIHL, picture thousands of tiny
hair cells standing up in a reservoir of fluid in the inner ear.
Disabling the gene caused a loss of outer
hair cells, a special sensory cell in the inner ear responsible for amplifying sound.
They succeeded in programming mouse stem cells to develop into immature
hair cells.
