Origin of inner ear hair cells: morphological and functional differentiation from ciliary cells into hair cells in zebrafish inner ear.
Auditory and vestibular functions in vertebrates depend on the transduction of sound vibration or head acceleration into electrical responses in inner ear hair cells. Mechanoelectrical transduction occurs at the tip of stereocilia, which are polarized to form an orientational arrangement that determines directional sensitivity. It remains to be clarified when and how premature hair cells acquir...
متن کاملTriggers of hair cell regeneration in the avian inner ear.
We performed an in vitro study in order to determine possible triggers of hair cell regeneration in the chick basilar papilla following degeneration. We compared the response of sensory epithelium damaged by collagenase treatment with that damaged by acoustic trauma. The former exhibited no proliferative activity, but the latter did. The basilar papillae damaged by acoustic trauma could have pr...
متن کاملTranscription factors in the development of inner ear hair cells.
Inner ear hair cells are the sensory receptors that detect and convert sound vibrations and head movements into neural signals. However, in humans, these cells are unable to regenerate if they are damaged or lost. Over thepast decade,there has been an exponential increase in interest and progress in understanding of the development of the inner ear and of hair cells, aiming to gain insights int...
متن کاملInner ear: dye injection reveals peripheral origins of specific sensitivities.
In the American bullfrog (Rana catesbeiana) tracing of functionally identijied, dye-filledjibers of the eighth cranial nerve to their peripheral origins has provided the jirst precise functional overlays for the microstructural maps of innerear sensory surfaces. The inner ear of the frog comprises eight sensory surfaces and the various structures accompanying each of them (I). Certain features ...
متن کاملHair Cell Bundles: Flexoelectric Motors of the Inner Ear
Microvilli (stereocilia) projecting from the apex of hair cells in the inner ear are actively motile structures that feed energy into the vibration of the inner ear and enhance sensitivity to sound. The biophysical mechanism underlying the hair bundle motor is unknown. In this study, we examined a membrane flexoelectric origin for active movements in stereocilia and conclude that it is likely t...
