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

...s. Identification of the stem cells from the adult cochlea would be a major step forward to develop new thera...eural progenitors. 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...

Noise echoes in cell communications

...artificially increasing the amount of noise in the cochlea of the inner ear, perhaps by an implanted device. Hong, Saidel and Martin applied this principle of noise to another process called "quorum sensing" ?how bacteria signal one another to act collectively when causing an infection. The Rutgers-Camde...

St. Jude study solves mystery of mammalian ears

Protein motor in cochlea hair cells dominates the process of sound amplific...r hair cells’ cilia to incoming sound waves in the cochlea fluid. Instead, somatic motility itself appears to dominate the amplification process in the mammali...
