Cochlear Nerve and Cochlear Nucleus
1975The first recordings of single neurone activity in the auditory system were made from the cochlear nucleus of the cat, by Galambos and Davis (1943). In these experiments the authors were attempting to record from fibres in the cochlear nerve; subsequently, however, they concluded that the recordings had been from aberrant cells of the cochlear nucleus ...

Morphometric Analysis of the Cochlear Nerve in Man
Acta Oto-Laryngologica, 1992Fiber diameters were analyzed in the meatal segment of the cochlear nerve from 7 temporal bones obtained from 7 patients. Two patients had normal hearing for their age. Two had sustained noise exposure and one had presbyacusis of predominantly neural type. The cochleae displayed characteristic degeneration patterns.

Involvement of Cochlear Nerve in Acoustic Tumours
Acta Oto-Laryngologica, 1990With conventional light and transmission electronmicroscopy we studied 10 cases of acoustic nerve tumour, 3 of which proved to be instances of von Recklinghausen neurofibroma and 7 of schwannoma. Schwannomas were not found to infiltrate the cochlear nerve.

Patterns of degeneration in the human cochlear nerve
Hearing Research, 1995The patterns of neural degeneration of the spiral ganglion were studied in 12 human pathologic specimens and 2 normal neonatal specimens. Morphometric analysis of spiral ganglion cells included the maximum cross-sectional areas of both large (type 1) and small (type II) spiral ganglion cells.

The Cochlear Nerve in Various Forms of Deafness
Acta Oto-Laryngologica, 1984Operative specimens of cochlear nerve of 56 patients with profound deafness of varying origin were examined under the light microscope and the number of myelinated nerve fibers in each specimen was counted. The transverse fascicular area of each nerve was also determined.

Unilateral Cochlear Nerve Deficiency in Children
Otolaryngology–Head and Neck Surgery, 2013ObjectiveCochlear nerve deficiency (CND) is increasingly diagnosed in children with sensorineural hearing loss (SNHL). We sought to determine the prevalence of CND, its imaging characteristics, and correlations with audiologic phenotype in children with unilateral SNHL.DesignCase series with chart review.SettingTertiary pediatric hospital.Subjects ...

Quantitative Evaluation of the Human Cochlear Nerve
Acta Oto-Laryngologica, 1990In 18 human temporal bones of patients with normal hearing or sensory neural deafness, the cochlear neurons were evaluated at the level of the peripheral axons in the osseous spiral lamina, the ganglion cells in the spiral ganglion and the central axons in the cochlear nerve in the inner acoustic meatus.

Anastomoses of the Vestibular, Cochlear, and Facial Nerves
Journal of Craniofacial Surgery, 2012The internal auditory canal (IAC) is 10 to 17 mm in length, and the facial nerve and vestibulocochlear nerve, which consist of the cochlear nerve, the superior vestibular nerve, and the inferior vestibular nerve, run together in the IAC packaged in dura mater.

Cochlear nerve fiber responses: Distribution along the cochlear partition
The Journal of the Acoustical Society of America, 1975Fourier analysis of discharge patterns in response to sinusoidal acoustic stimulation provides a consistent and repeatable measure of response phase and amplitude. The distribution of the fundamental components of response for large populations of fibers as a function of their characteristic frequency provides a link between the spatiotemporal ...
