Structure and innervation of the cochlea

Y Raphael, RA Altschuler - Brain research bulletin, 2003 - Elsevier
The role of the cochlea is to transduce complex sound waves into electrical neural activity in
the auditory nerve. Hair cells of the organ of Corti are the sensory cells of hearing. The inner …

The spiral ganglion: connecting the peripheral and central auditory systems

BA Nayagam, MA Muniak, DK Ryugo - Hearing research, 2011 - Elsevier
In mammals, the initial bridge between the physical world of sound and perception of that
sound is established by neurons of the spiral ganglion. The cell bodies of these neurons …

Chronic electrical stimulation by a cochlear implant promotes survival of spiral ganglion neurons after neonatal deafness

PA Leake, GT Hradek, RL Snyder - Journal of Comparative …, 1999 - Wiley Online Library
This investigation examined the consequences of neonatal deafness and chronic
intracochlear electrical stimulation delivered by a cochlear implant during maturation. Kittens …

Deafness-induced changes in the auditory pathway: implications for cochlear implants

RK Shepherd, NA Hardie - Audiology and Neurotology, 2002 - karger.com
A profound sensorineural hearing loss induces significant pathological and atrophic
changes within the cochlea and central auditory pathway. We describe these deafness …

Intraocular elevation of cyclic AMP potentiates ciliary neurotrophic factor-induced regeneration of adult rat retinal ganglion cell axons

Q Cui, HK Yip, RCH Zhao, KF So, AR Harvey - Molecular and Cellular …, 2003 - Elsevier
In vitro, cyclic AMP (cAMP) elevation alters neuronal responsiveness to diffusible growth
factors and myelin-associated inhibitory molecules. Here we used an established in vivo …

Tissue engineering strategies for spiral ganglion neuron protection and regeneration

B Zhang, Y Hu, H Du, S Han, L Ren, H Cheng… - Journal of …, 2024 - Springer
Cochlear implants can directly activate the auditory system's primary sensory neurons, the
spiral ganglion neurons (SGNs), via circumvention of defective cochlear hair cells. This …

Functional role of neurotrophin-3 in synapse regeneration by spiral ganglion neurons on inner hair cells after excitotoxic trauma in vitro

Q Wang, SH Green - Journal of Neuroscience, 2011 - jneurosci.org
Spiral ganglion neurons (SGNs) are postsynaptic to hair cells and project to the brainstem.
The inner hair cell (IHC) to SGN synapse is susceptible to glutamate excitotoxicity and to …

Ultrasound enhances the expression of brain-derived neurotrophic factor in astrocyte through activation of TrkB-Akt and calcium-CaMK signaling pathways

SH Liu, YL Lai, BL Chen, FY Yang - Cerebral cortex, 2017 - academic.oup.com
Low-intensity pulsed ultrasound (LIPUS) stimulation has been shown to increase the
expression of brain-derived neurotrophic factor (BDNF) in astrocytes of an in vitro model and …

Chronic depolarization enhances the trophic effects of brain‐derived neurotrophic factor in rescuing auditory neurons following a sensorineural hearing loss

RK Shepherd, A Coco, SB Epp… - Journal of Comparative …, 2005 - Wiley Online Library
The development and maintenance of spiral ganglion neurons (SGNs) appears to be
supported by both neural activity and neurotrophins. Removal of this support leads to their …

Cellular mechanisms associated with spontaneous and ciliary neurotrophic factor-cAMP-induced survival and axonal regeneration of adult retinal ganglion cells

K Park, JM Luo, S Hisheh, AR Harvey… - Journal of Neuroscience, 2004 - jneurosci.org
We have shown previously that intraocular elevation of cAMP using the cAMP analog 8-(4-
chlorophenylthio)-cAMP (CPT-cAMP) failed to promote axonal regeneration of axotomized …
