How fish hear and make sounds at same time
...tes, including mammals. While humans hear with the cochlea of the inner ear, the midshipman uses the sacculus, a part of the ear that in humans detects acceleration or linear movement. Because the study indicates a relationship between the ear and the auditory and vocalization systems of the brain, it could...Sooner is better with cochlear implants, Stanford scientist shows
...rical stimulation that the implants provide to the cochlea as sound. A Stanford neurobiologist teamed with child-development specialists at the University of Maryland to see if children with cochlear implants were able to meld their newly acquired hearing capability with their ability to read lips. In other...Critical hearing gene helps send auditory messages to brain

They now report that otoferlin activity in the cochlea occurs only in the inner hair cells, where it conc...onvert them into electrical signals, bypassing the cochlea to directly stimulate the auditory nerves. "That's good news," Petit said, since otoferlin-linked ...Study shows isolation of stem cells may lead to a treatment for hearing loss

This led us to hypothesize that cochlea harbors stem cells and neural precursor cells. Our work in collaboration with Miller’s lab supports ...Scientists identify molecular cause for one form of deafness
...which are used in flat-panel displays. Within the cochlea of the inner ear, sound waves cause the basilar membrane to vibrate. These vibrations stimulate hair cells, which then trigger nerve impulses that are transmitted to the brain. Researchers have now learned that mutations in a protein called espin c...Gene Therapy To Treat Deafness
...often associated with loss of sensory hairs in the cochlea due to age, infection or disease. Hearing loss becomes incurable, as the lost sensory hair cells do not regenerate. The new gene therapy may be able to cause clinically deaf people to get back some part of their hearing sensations. Tested on guinea...Hearing loss can happen from regular exposure to carbon monoxide
...ide can cause oxidative stress that may damage the cochlea of the inner ear of the younger ones and cause permanent damage to hearing abilities of young rats. Carbon monoxide at the exposure limit of 0.0025% in air can cause oxidative stress for the children. Oxidative stress happens when the free radicals...Studies On Hearing Loss Discovers New Causes
...study to quantitatively analyze the changes in the cochlea due to type 1 diabetes mellitus. The researchers ...type 1 diabetes mellitus results in changes of the cochlea which are likely to result in hearing loss.

...ed that the PCP pathway is involved in shaping the cochlea and the sensory hair cells. Mutations within this genetic pathway impair the shape of the cochlea and the polarity of the sensory hair cells that are essential for hearing.......rceived as sound," said Kathuria. When the damaged cochlea is bypassed by the implant and the intact neurons are stimulated, hearing can be restored. But the implants do not come cheap - the most economical models cost between Rs.600,000 and 700,000. Over 1,00,000 implants have been done worldwide since the...
