spiral ganglion

The post-synaptic neurite then sends an action potential to the spiral ganglion.

The fibers connecting the spiral ganglion with the central nervous system form the cochlear nerve.

Type II spiral ganglion cells make up the remainder.

The spiral ganglion is situated inside it.

Two apparent subtypes of spiral ganglion cells exist.

Spiral ganglion neurons are particularly sensitive to neurotrophic factor-3 (NT-3).

Common targets include spiral ganglion and Organ of Corti.

From here, the Organ of Corti and spiral ganglion may be removed with forceps.

It was found that some months after the organ of Corti had degenerated, the spiral ganglion also began to degenerate.

The spiral ganglion neurons contain the cell bodies of the auditory primary afferent fibers.

These stimulate the spiral ganglion, which sends information through the auditory portion of the eighth cranial nerve to the brain.

The ganglion gradually splits into two parts, the vestibular ganglion and the spiral ganglion.

The cell bodies of the cochlear nerve lie within the central aspect of the cochlea and are collectively known as the spiral ganglion.

The cell bodies of the spiral ganglion neurons are found in the modiolus, the conical shaped central axis in the cochlea.

Each fiber is an axon of a spiral ganglion cell that represents a particular frequency of sound, and a particular range of loudness.

The movement the basilar membrane displaces the inner hair cells in one direction, which encodes a half-wave rectified signal of action potentials in the spiral ganglion cells.

Neurons whose cell bodies lie in the spiral ganglion are strung along the bony core of the cochlea, and send fibers (axons) into the central nervous system (CNS).

Consistent with an apparent absence of mature hair cells, initial work suggested that all vestibular and most spiral ganglion cells are lost by postnatal day 14 (P14; [ 1 ] ).

In addition, outer hair cells form reciprocal synapses onto Type II spiral ganglion cells, suggesting that the Type II cells have both afferent and efferent roles.

The terms "cochlear nerve fiber" and "spiral ganglion cell" are used, to some degree, interchangeably, although the former may be used to more specifically refer to the central axons of the cochlear nerve.

Axons from the spiral ganglion cells of the lower frequencies innervate the lateral-ventral portions of the dorsal cochlear nucleus and the ventrolateral portions of the anteroventral cochlear nucleus.

This potential derived from the CM initiates chemical processes in hair cells that lead to the release of neurotransmitters in the synaptic cleft between the hair cells and the spiral ganglion neurons.

Type I spiral ganglion cells comprise the vast majority of spiral ganglion cells (90-95% in cats and 88% in humans), and exclusively innervate the inner hair cells.

The LOCS (originating from both the intrinsic and shell neurons) contains unmyelinated fibres that synapse with the dendrites of the Type I spiral ganglion cells projecting to the inner hair cells.

By RNA in-situ hybridization, Sobp expression in neonatal tissue was demonstrated in spiral ganglion, the sensory and supporting cells of the maculae of saccule and maculae of utricle, and cristae ampullaris.
