The polarity of each cell was analyzed in those neuromasts in which each kinocilia and stereocilia could be clearly identified.
Researchers found that CIB2 staining is often brighter at shorter row stereocilia tips than the neighboring stereocilia of a longer row, where it may be involved in calcium signaling that regulates mechano-electrical transduction, a process by which the ear converts mechanical energy-or energy of motion-into a form of energy that the brain can recognize as sound.
The stereocilia are rooted in a gel-like cuticle on the top of the cell that is believed to act as a rigid platform, helping the hairs return to their resting position.

However, if exposure to noise continues, hairs get tangled and start to lose their stereocilia.
This has about 17,000 small hair cells, and each one has tiny hair-like structures called stereocilia, which project into the cochlea fluid.
Thirty to 300 stereocilia form a hair bundle, which is the mechanoreceptive structure of the hair cell.
During a TTS, the stereocilia of the outer hair cells become less stiff and disarrayed, responding poorly to stimulation.
Bundles of gently waving stereocilia serve as receptacles for sound waves delivered from hair cells, transforming those waves into electrical signals that travel to the brain to be interpreted.
curriculum includes construction of a sound thermometer, spaghetti and Play-doh model of stereocilia, and demonstrations of proper usage of hearing protection.
Sound vibrations cause the stereocilia to bend slightly, and scientists think the movement opens small pores, called ion channels.
