RehabilitationCochlear implant users of all ages can practice speaking and listening skills with interactive and downloadable (re)habilitation activities. Any problem in the outer or middle ear that prevents sound from being conducted properly is known as a conductive hearing loss. Sensorineural hearing loss results from missing or damaged sensory cells (hair cells) in the cochlea and is usually permanent.
Mild to severe sensorineural hearing loss can often be helped with hearing aids or a middle ear implant. A problem that results from the absence of or damage to the auditory nerve can cause a neural hearing loss. Hearing aids and cochlear implants cannot help because the nerve is not able to pass on sound information to the brain.
Researchers have tracked a cell-to-cell signaling pathway that designates the future location of the ear's sensory organs in embryonic mice.
The results suggest an avenue for further investigation in restoring hearing loss from nerve damage.
The findings are reported this week in the early online edition of Proceedings of the National Academy of Sciences by researchers Byron H.

The goal of their research is to develop ways to restore inner ear sensory hair cells in people who have lost them due to age, excessive noise or other toxic damage.
The first stage in the normal development of hair cells is called prosensory specification. Byron Hartman, a postdoctoral fellow in the Bermingham-McDonogh lab, found that a signaling system called the Notch pathway is important in laying the foundation for the inner ear sensory hair cells and their associated supporting cells. If ways could be found to safely re-start particular Notch signals in adults, therapies might be designed to regenerate specific tissues, like nerves, and thereby repair damage and restore lost function, like hearing. Neither the service provider nor the domain owner maintain any relationship with the advertisers. The scientists succeeded in activating this signal more widely across the embryonic tissue that becomes the inner ear. Hartman, Thomas Reh, and Olivia Bermingham- McDonogh of the Department of Biological Structure at the University of Washington (UW) in Seattle. The hair cells do not spontaneously recover after they are lost, and adult stem cells have not been found in the mammalian inner ear. In the growing embryo, regions of the ear-forming tissue are selected to become the inner ear organs that detect sound and allow for our sense of balance. The researchers were able to activate the Notch pathway in regions of the inner ear that would normally never make hair cells and convert these regions to patches of new sensory tissue. They collect information at the cell surface and report to the cell's operations center, the nucleus.
Perhaps this knowledge, they noted, may lead to ideas on how to re-create this earlier state in the mature adult ear to stimulate re-growth of the cells critical to hearing. In case of trademark issues please contact the domain owner directly (contact information can be found in whois).

This process ensures that without your approval, data will not be transferred to the social networks. In order to devise a way to restart hair cell formation in the adult ear, Bermingham-McDonogh's group is studying how hair cells are made in the first place during ear development.
In other words, they could encourage the formation of new building foundations throughout the inner ear. The structures contained tufted cells, called hair cells, which respond to sound waves and other sensations, and additional nerve cells that amplify or code sounds for the brain to interpret. The senior author, Bermingham-McDonogh, is also an affiliate of the UW Virginia Merrill Bloedel Hearing Research Center. All the subsequent, complex steps in the construction of the building require a solid foundation. Once these new sensory patches were made, new hair cells and support cells were properly produced within them. More recently scientists in the regenerative medicine field have begun taking advantage of this key regulatory signal to restart developmental processes in adults.
So by starting the ball rolling with the Notch signal, the researchers observed that the rest of the developmental processes followed along correctly.
