Participation of the lateral geniculate body in mechanisms of brain activation [PDF]
Neuroscience and Behavioral Physiology, 1985 The significance of the lateral geniculate body for nonspecific activation of the brain was elucidated in experiments on cats. It was established that when the connections of the lateral geniculate body remain intact, its stimulation elicits the usual activation of the EEG, but at higher threshold values of the current (120-190 microA) than when 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.

Subcortical projections to the lateral geniculate body in the rat
Experimental Brain Research, 1982The subcortical projections to the lateral geniculate body (LGB) in the rat were studied by means of discrete HRP iontophoretic deposits in the dorsal or the ventral LGB; the labelling was compared to that resulting from HRP deposits in neighboring nuclei.

CONNECTIONS OF THE MEDIAL GENICULATE BODY IN THE CAT [PDF]
Archives of Neurology And Psychiatry, 1941 It has been reported1that after complete decortication in the dog auditory acuity is appreciably impaired but acoustic function is by no means obliterated. Furthermore, such an animal can be differentially conditioned to pure tone (1,000 cycles) and complex sound (electric bell).

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

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.

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,

Postnatal cytoarchitecture of the rat medial geniculate body
The Journal of Comparative Neurology, 1998The medial geniculate body (MGB) is a thalamic structure that provides vital information flow to the forebrain for complex acoustic processing. The development of cytoarchitectural features of the MGB was examined in rat to identify age-related patterns of growth in major geniculate compartments that have been described previously (Clerici and Coleman [

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 ...
