Ossification of the basal turns of both cochleas was confirmed intraoperatively.
In addition, a partial loss of constructive interference in a steady state (CISS) signal was noted in the basal turn and the middle turn (figure 2, A) of the cochlea.
In our case the initial CT scan failed to demonstrate ossification of the cochlea, showing patency of both cochleas.
The procedure was abandoned and a subsequent high resolution CT scan showed complete ossification of the left cochlea and but a patent cochlea on the right (Fig.
The Cochlea is a part of human ear where a transmission of acoustics signals into electrical signals takes place.
Longitudinal pattern of basilar membrane vibration in the sensitive cochlea, Proceeding of the National Academy of Science of the United States of America, Vol.
To test the idea, Darlene Ketten, a biologist at Woods Hole Oceanographic Institution (WHOI), and WHOI researcher Julie Arruda provided high-resolution CT scans, taken at the WHOI Computerized Scanning and Imaging Facility, of cochleas from 13 different land and mammal species.
From the CT images, Ketten's group made precise geometric measurements of all the cochleas and sent the images, drawings, and data to a research team led by Daphne Manoussaki, a mathematics professor at Vanderbilt University, and Richard S.
Then, a long-term study on 26 ears found that all cochleas had an increase in click-evoked auditory brainstem response thresholds for the first 4 weeks.
Cochlear implantation in children: labyrinthitis following pneumococcal otitis media in unimplanted and implanted cat cochleas.
To test whether extra copies of Math 1 might boost hair cell production, the Genentech researchers exposed cells from rat cochleas to a DNA ring, or plasmid, containing the Math 1 gene.
At birth, the cochleas of rats are still quite immature, even though they already have formed most of their hair cells, she says.
Inside the cochlea reside microscopic hair cells that bend and, due to sound vibrations or changes in resistance, create electrical signals that are passed on to the auditory nerve and then to the brain.
Losses that occur in the inner ear--from the cochlea on--are referred to as sensorineural losses.
Miyamoto is referring to cochlear implants--a revolutionary technology that can be used when the snail-shaped organ in the inner ear called the cochlea
