Inhibition in the medial geniculate body of the cat
Experimental Brain Research, 19691. Inhibitory activity in the cat medial geniculate body (MG) was examined by stimulating electrically and acoustically the input and output of the MG. 2. A longer and more profound depression of excitability occurs following a click-evoked potential in the MG than in the inferior colliculus (IC) in both anesthetized and unanesthetized ...

The geniculate bodies are nuclear masses belonging to the dorsal thalamus that have detached from it during ontogeny and are therefore designated as the metathalamus. They comprise two major structures: the lateral geniculate nucleus (LGN) related to the visual system, and the medial geniculate nucleus, a part of the auditory system.

THE EXTERNAL GENICULATE BODIES
Archives of Neurology & Psychiatry, 1940The presence of macula-sparing hemianopia after lesions of the occipital lobe is not an uncommon finding. Localized areas of softening in the anterior portion of the calcarine fissure without involvement of the optic radiation produce this type of defect in the visual field and may be readily explained by the absence of pathologic changes in the ...

Inhibitory Processes In The Medial Geniculate Body
Acta Oto-Laryngologica, 1975Inhibition in the medial geniculate body was studied with a double click technique. A conditioning click caused a marked inhibition of field potentials and unit discharges to a subsequent test click. Cyclic inhibition with a period of about 150 ms was seen in the medial geniculate body and the auditory cortex, but not in the inferior colliculus.

Neural architecture of the rat medial geniculate body
Hearing Research, 1999The rat medial geniculate body was subdivided using Nissl preparations to establish nuclear boundaries, with Golgi-Cox impregnations to identify projection and local circuit neurons, and in fiber stained material to delineate the fiber tracts and their distribution.

GABAergic organization of the cat medial geniculate body
The Journal of Comparative Neurology, 1999A study of neurons and processes (puncta) immunolabeled by antibodies to gamma-aminobutyric acid (GABA) or glutamic acid decarboxylase was undertaken in the medial geniculate body of the adult cat. The proportion and types of GABAergic cells were determined with high resolution methods, including postembbedding immunocytochemistry on semithin plastic ...

Cortical projections of the medial geniculate body in the cat
Experimental Brain Research, 1974Unilateral stereotaxic lesions were placed in the medial geniculate body (MGB) in 13 cats, and the ensuing axon degeneration was traced to the cerebral cortex by the method of Nauta and Gygax (1954). The anterior and middle portions of the principal part have heavy projections to the middle ectosylvian gyrus (AI), the lateral bank of the middle ...

Injury of the lateral geniculate body in an amateur boxer
Neuro-Ophthalmology, 2000A 26-year-old amateur boxer noticed a visual field defect without an apparent temporal correlation with a fight. Computerized perimetry showed right inferior homonymous quadrantopsia and congruous horizontal sectoranopia. Magnetic resonance imaging revealed a CSF-filled cavity in the left lateral geniculate body, which was surrounded by a rim of signal

Steady potential responses in the lateral geniculate body
Electroencephalography and Clinical Neurophysiology, 1955Abstract 1. 1. Repetitive electrical stimulation of the optic nerve produces a steady potential field in the region of the dorsal nucleus of the lateral geniculate body of the cat which persists for as long as 5 sec. after the end of stimulation. 2. 2. The amplitude of this steady potential response at a given point is an approximately linear,

HISTOPATHOLOGY OF THE EXTERNAL GENICULATE BODY
Archives of Neurology And Psychiatry, 1934The external geniculate body has been studied extensively in numerous investigations of the central visual system, but such research has been concerned largely with the anatomy of the fibers and the representation of the retina in the central nervous system.
