The vestibular ganglion of cat contains two distinguishable cell types, the larger and myelinated of which are much more numerous.


How mechanical information is encoded in the vestibular periphery has not been clarified. To begin to address the issue we examined the intrinsic firing properties of postnatal mouse vestibular gan

The role of sodium (Na V) channels in this diversity has not been investigated because Na V currents in rodent vestibular ganglion neurons (VGNs) were reported to be homogeneous, with the voltage dependence and tetrodotoxin (TTX) sensitivity of most neuronal Na V channels. 11.1 Overview of Ascending and Descending Pathways. The first-order vestibular afferents have their cell bodies in the vestibular (Scarpa’s) ganglion, which is found at the distal end of the internal auditory meatus.Their axons travel in the vestibular portion of the VIIIth cranial nerve through the internal auditory meatus and enter the brain stem at the junction between the pons and the 2021-04-11 Objectives/Hypothesis: Vestibular neuritis is a common cause of both acute and chronic vestibular dysfunction. Multiple pathologies have been hypothesized to be the causative agent of vestibular neuritis; however, whether herpes simplex type I (HSV1) reactivation occurs within the vestibular ganglion has not been demonstrated previously by experimental evidence. The most characteristic histopathology of vestibular neuritis in the human temporal bone is degeneration of the superior vestibular nerve and vestibular ganglion with variable involvement of the neuroepithelium of the end organs and a deficiency in the population of the nerve fibres and microscopic findings of myelin degeneration.

In vertebrates, ganglia are usually located outside the brain or spinal cord and control the functioning of the body's internal organs. The vestibular ganglion houses the cell bodies of the bipolar neurons and extends processes to five sensory organs. Three of these are the cristae located in the ampullae of the semicircular canals. Hair cells of the cristae activate afferent receptors in response to rotational acceleration. The vestibular nerve is one of the two branches of the vestibulocochlear nerve.

Pulsed infrared radiation (IR) has previously been shown to elicit responses in neurons. This study analyzes the response of neonatal rat spiral and vestibular ganglion neurons in vitro to IR (wavelength = 1,863 nm) using Ca(2+) imaging.
