![]() Measurements of activity at the brain site and at the auditory-nerve fibers were taken at days 1, 5, 10 and 30 following the induced injury. Researchers in UB's Center for Hearing and Deafness induced reversible damage to the auditory-nerve endings in the cochlea, the primary sensory organ of the inner ear, in eight chinchillas, and monitored auditory-signal transmission between the damaged nerve and the location in the brain that receives its signals. ![]() The finding of central-auditory-system plasticity also may explain why many hearing-aid users go through an adjustment period before they perceive an improvement, McFadden said. This may be important with regard to restoring hearing in humans, through the use of hearing aids or cochlear implants, for example, because it demonstrates that the brain remains plastic after a period of sensory deprivation." "What is new here," she said, "is our finding that the brain can reorganize itself again after the peripheral sensory organ recovers from damage and sensory input is restored. "That has been shown in many previous studies in which permanent damage has been created by surgery, drugs or aging. "It is not news that the brain can reorganize itself after damage to the peripheral sensory organ," said Sandra McFadden, Ph.D., research scientist in UB's Center for Hearing and Deafness and an author of the study. ![]() 16) at the annual meeting of the Association for Research in Otolaryngology. Results of the study were presented here today (Monday, Feb. The findings have important implications for restoring lost hearing in humans. They also found that the damaged nerve endings that transmit impulses from hair cells to the brain can recover from injury, but at a significantly slower rate than the brain. The brain center responsible for hearing retains the ability to reorganize itself and respond normally during periods of reduced activity resulting from damage to the auditory nerve endings in the inner ear, a study by University at Buffalo researchers has shown. Send us feedback about these examples.ST. These examples are programmatically compiled from various online sources to illustrate current usage of the word 'auditory nerve.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. Andrew Grant, Discover Magazine, 27 June 2010 The signals from these cells are passed to the auditory nerve and decoded in the brain. 2021 In a sense, cyborgs already walk among us: Nearly 200,000 deaf or near-deaf people have cochlear implants, electronic sound-processing machines that stimulate the auditory nerve and link into the brain. Holly Barker, Discover Magazine, 3 Nov. 2010 Smoking can harm hearing in other ways, such as through alterations in auditory nerve signalling or by causing damage to the tiny hairs inside the ear. Carl Zimmer, Discover Magazine, 26 Oct. 2012 That is why tinnitus often doesn’t go away when people get their auditory nerve surgically cut. Jeremy Hillpot, Discover Magazine, This type of hearing loss, which affects many people, is currently untreatable it isn’t helped by hearing aids or cochlear implants, both of which depend on the auditory nerve to send the final signals to the brain. 2023 The electric charge stimulates the auditory nerve. ![]() Jennifer Ouellette, Ars Technica, 22 Mar. 2011 Beethoven-Haus Bonn An autopsy identified severe liver damage (evidence of cirrhosis) as the likely cause of death and significant dilation of the auditory nerve. Christopher Linstrom, Discover Magazine, 31 Jan. Recent Examples on the Web For the middle ear muscle reflex, the afferent limb is the auditory nerve the efferent limb is the facial nerve for the stapedius muscle and the trigeminal nerve for the tensor tympani muscle. ![]()
