8 All AN patients did not show loudness recruitment, indicating that the auditory nerve
transmission pathway of AN was affected.
The increased IPL which was observed in elderly individuals could be due to degenerative changes such as auditory nerve
atrophy, synaptic delay, and peripheral hearing loss with age.
My audiologist activated the first MAP, which is a program that calibrates how much input each electrode (22 in my case) transmits to the auditory nerve
The device, like a minimicrophone, bypasses the damaged parts of the ear and stimulates the auditory nerve
Cochlear fluid mechanics, the equivalent of glottal airflow mechanics in vocalization, excites the hair cells to transmit electrical signals to the brain via the auditory nerve
Wave I is produced by the acoustic nerve activity that wave II can reflect the activity of the cochlear nucleus with a contribution from the auditory nerve
, that Wave III can be referred to the generators in the superior olivary complex and the lateral leminiscii, that the wave IV-V complex is generated in the axons and/or nuclei of the lateral leminiscii and probably also from inferior colliculi.
They are then transmitted to the inner ear where tiny hairs in the cochlea (a snail-shaped organ) transform them into nerve impulses carried to the brain by the auditory nerve
The implant utilizes electrical stimulation of the auditory nerve
to enable the patient to hear, and those electronics are placed in either a ceramic or cast titanium housing, although titanium has grown in preference due to the material's leak tightness and impact strength.
Supplementing the 1200 images within the book are 15 outstanding videos available on Thieme's MediaCenter demonstrating the implantation of the diﬀerent cochlear implantation devices that are currently available and the application of brainstem implants in these situations: tumor removal, malformation (missing auditory nerve
in children), and cochlear ossification.
Here, millions of tiny hair cells are stimulated to release glutamate at synapses with the auditory nerve
, triggering impulses to fire along the auditory nerve
to the brain.
Among the topics are temporal coding in the auditory cortex, white-matter pathways for speech and language processing, hemodynamic imaging of the auditory cortex, neurocognitive development in congenitally deaf children, deafness in cochlear and auditory nerve
disorders, auditory neglect and related disorders, and hearing disorders in multiple sclerosis.
Many children born deaf benefit from cochlear implants, electrodes that send impulses to the auditory nerve
, where they're relayed to the brain and recognized as sound.
The AAO's new guidelines, published in the October issue of Otolaryngology-Head and Neck Surgery, recommend that for bothersome, persistent tinnitus, you should undergo an exam with a medical doctor, such as an ear, nose and throat specialist, to rule out any treatable medical conditions, such as benign tumors on the auditory nerve
, earwax buildup, or jaw problems.
The parents said the doctor opened the child's right ear but failed to properly implant new devices that transmit sound directly to her auditory nerve
It has demonstrated that physical changes in myelin itself -the coating of the auditory nerve
carrying sound signals to the brain -- affect our ability to hear.
