Geniculate Ganglion Anatomy for the Otologist
Archives of Otolaryngology - Head and Neck Surgery, 1969THE greater (superficial) petrosal nerve and the geniculate ganglion are major anatomic landmarks in the surgical approach to the internal auditory canal through the middle cranial fossa. 1 The dura is elevated from the superior surface of the temporal bone through a craniectomy just above the root of the zygomatic process.

Lateral Geniculate Nucleus in Glaucoma
American Journal of Ophthalmology, 1993To assess glaucomatous damage to the lateral geniculate nucleus of the thalamus, as well as to its magnocellular and parvocellular layers, we examined the autopsy sections of the lateral geniculate nucleus of individuals with and without glaucoma.

We applied tests of antidromic activation to identify cells in the hamster intergeniculate leaflet (IGL) that project to either the suprachiasmatic nucleus (SCN) or the contralateral IGL. IGL cells projecting to these targets were tested for photic responses; most showed sustained activation, while a few were suppressed by retinal illumination ...

Surgical Anatomy Of The Geniculate Ganglion
Acta Oto-Laryngologica, 1975The position and the average dimensions of the geniculate ganglion have been measured with the Zeiss screw micrometer in 24 temporal bones obtained from the histological collection of the ENT department of the University of Zurich. The geniculate ganglion has been found to lie like a cup over the anterior portion of the genu of the VII nerve.

Neurotrophin receptors in the geniculate ganglion
Molecular Brain Research, 1999We examined the distribution of the high affinity neurotrophin receptors (trkA, trkB, and trkC) in the rat geniculate ganglion. Previous work had shown that during early (prenatal) development, trkB and its two ligands, BDNF and NT-4/5, were most important for survival of almost all neurons.

Ventral lateral geniculate nucleus projects to the dorsal lateral geniculate nucleus in the cat
NeuroReport, 2005The lamina C3 of the dorsal lateral geniculate nucleus of the cat does not receive retinal projections but instead receives visual information from the small subpopulation of W-type ganglion cells via the upper substratum of the stratum griseum superficiale of the superior colliculus.

Influence of the cortico-geniculate pathway on response properties of cat lateral geniculate neurons
Brain Research, 1981The influence of the cortico-geniculate pathway on identified X and Y lateral geniculate cells was studied by reversibly cooling visual cortical areas 17 and 18. The majority (86.5%) of cells changed their response to visual stimulation when cortex was inactivated, and both X- and Y-cells were modulated by the cortical input.

The human medial geniculate body
Hearing Research, 1984The medial geniculate body in non-human species is divided into several parts, each with a different structure, physiological organization, and pattern of connections. Which parts of the human medial geniculate body and which types of neurons might be homologous to those of other species is unknown, and the object of the present study.

Herpetic geniculate ganglionitis
Acta Neuropathologica, 1962A case is described of a 76-year old woman with left-sided herpes oticus, herpes facialis and facial palsy. Post-mortem examination showed herpetic inflammation of the left Gasserian ganglion and geniculate ganglion. This is the first histological evidence of the involvement of the geniculate ganglion in herpes zoster oticus.

In the present study, we examined the distribution of calretinin-immunoreactive neuronal cell bodies and fibers in the lateral geniculate nucleus of the rat. In normal rats, clusters of immunoreactive cell bodies were found in: (i) the rostral portion of the ventral lateral geniculate nucleus pars medialis (VLGM), (ii) the intergeniculate leaflet (IGL),
