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 ...

Projections of auditory cortex to the medial geniculate body of the cat
The Journal of Comparative Neurology, 2000The corticofugal projection from 12 auditory cortical fields onto the medial geniculate body was investigated in adult cats by using wheat germ agglutinin conjugated to horseradish peroxidase or biotinylated dextran amines. The chief goals were to determine the degree of divergence from single cortical fields, the pattern of convergence from several ...

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.

Binaural response patterns in subdivisions of the medial geniculate body
Brain Research, 1994Auditory evoked potentials (AEPs) to binaural click stimulation were examined in the ventral (MGv) and caudomedial (MGcm) subdivisions of the medial geniculate body (MG) in guinea pigs. Binaural stimulation caused a decrease in amplitude for the response component recorded from the MGv, but an increase in amplitude for the AEP component recorded from ...

Types of interneurons and their participation in the neuronal network of the medial geniculate body [PDF]
Experimental Brain Research, 1976 Three different types of interneurons can be separated in the Golgi picture, and many of their details can be identified under the electron microscope, in the medial geniculate body (MGB) of the cat: (1) typical short axon Golgi II. cells of the thalamic type, (2) somewhat larger Golgi type II cells with medium range axon, and (3) spidery neurogliform ...

Identification of subdivisions in the medial geniculate body of the guinea pig
Hearing Research, 2007The accurate and reliable identification of subdivisions within the auditory thalamus is important for future studies of this nucleus. However, in the guinea pig, there has been no agreement on the number or nomenclature of subdivisions within the main nucleus of the auditory thalamus, the medial geniculate body (MGB).

Neuronal connections in the medial geniculate body of the guinea-pig
Experimental Brain Research, 2000The spontaneous and evoked activities of individual pairs of single units were recorded simultaneously with the same microelectrode in the medial geniculate body (MGB) of ketamine-xylazine-anaesthetised guinea-pigs. Cross-correlograms (CCGs) of spike train pairs were computed and divided on the basis of correlation peak shape into four classes [a ...

Temporal Information in the Medial Geniculate Body
1981If some temporal information of acoustic signals is to be used and processed in the auditory cortex, it should be transfered through the medial geniculate body (MGB) with sufficient precision.

A Morphometric Comparative Study of the Medial Geniculate Body of the Rabbit and the Fox
Anatomia, Histologia, Embryologia, 2011Unbiased stereological methods were used to morphometrically examine and compare the medial geniculate body (MGB) of two species from different mammalian orders. The MGB had a similar nuclear pattern, and it was parcelled into three major cytoarchitectural areas: the dorsal nucleus (MGd), the ventral nucleus (MGv) and the medial nucleus (MGm).

Brain Research, 1974
(Accepted September 4th, 1974) The medial geniculate body of mammals is not a homogeneous structure, and has thus been subdivided into a varying number of component nuclei. On the basis of cytoarchitectonics and Golgi analysis, Cajal subdivided the medial geniculate body of a number of mammals into ventral, medial, and dorsal divisions a and, more ...
