Tonotopic organization in ventral nucleus of medial geniculate body in the cat
Journal of Neurophysiology, 1985Responses of single units and clusters of units to tone burst stimulation were recorded at 100-micron intervals along vertical electrode penetrations through the medial geniculate bodies of eight barbiturate-anesthetized cats. Marking lesions were placed at two or three locations along most penetrations to aid in histological reconstruction of ...

Physiological Properties of Neurons in the Medial Geniculate Body [PDF]
, 2010 An important synthesis of thalamic organization noted that: ‘…the thalamus has not had good press in the recent past’ (Sherman and Guillery 1996). The functional role of the auditory thalamus (medial geniculate body; MG) has been eclipsed by the enormous effort aimed at dissecting the properties of cortical neurons.

Auditory Cortical Projections to the Medial Geniculate Body
2010Although the thalamus is traditionally regarded as a simple relay station for sensory information reaching cerebral cortex from the periphery, growing evidence supports a new view: that it actively regulates the passage of sensory information and modulates sensory signals.

Contributions of medial geniculate body subdivisions to the middle latency response
Hearing Research, 1992Ongoing studies in our laboratory, concerned with identifying the neural pathways responsible for the auditory middle latency response (MLR), have involved analysis of surface and intracranial potentials following pharmacologic inactivation (with lidocaine) of small regions in the guinea pig brain.

Projections from the medial geniculate body to the cerebral cortex in the cat
Brain Research, 1969Stereotaxic lesions made in the MGB lead to the finding of Nauta-stained degeneration in the anterior, middle and posterior ectosylvian gyri, i.e., areas AI, AII, Ea, Ep, SF and I-T. Degeneration was not found in SII except in 2 brains in which the ventrobasal complex was probably involved in the lesion. There was no significant projection from the MGB

Subcortical projection of the magnocellular medial geniculate body of monkey
Journal of Comparative Neurology, 1970AbstractSubcortical projection of the magnocellular medial geniculate body to the lateral segment of the globus pallidus is suggested on the basis of anatomical observations in six Macaca mulatta. In two, extensive decortication failed to produce complete degeneration of the magnocellular division of the nucleus, suggesting the existence of a ...

Frequency organization and cellular lamination in the medial geniculate body of the rabbit
Hearing Research, 2001Cellular laminae within the tonotopically organized ventral division of the medial geniculate body (MGV) of the cat have been proposed as the anatomical substrate for physiologically defined isofrequency contours. In most species, the laminae are not visible with routine Nissl stains, but are defined by the dendritic fields of principal cells and the ...

Size and Duration of Inhibition in the Medial Geniculate Body in Unanesthetized Cats
Acta Oto-Laryngologica, 1976A method which allows repeated micro-electrode recordings from subcortical structures without using any drugs is described. This method was adopted in combination with convential implantation techniques to study click-evoked potentials and inhibitory processes in the auditory system of the cat.

Influence of the septum and inferior colliculus on medial geniculate body units
Electroencephalography and Clinical Neurophysiology, 1970Abstract The septum has been found to have direct projections to the medial geniculate body (MGB) and the inferior colliculus; this study was undertaken to determine whether or not the septum might influence the function of the MGB. Excitatory and inhibitory effects on MGB unit firing were observed after stimulation of the septum and inferior ...

Transmission delay of phase-locked cells in the medial geniculate body
Hearing Research, 1980Over 4000 single unit recordings were obtained from the medial geniculate body (MGB) of nitrous oxide anaesthetized cats. Out of 1600 cells sensitive to tone bursts below 4 kHz, 10% were responding in a sustained manner. From these, 121 were tested for phase-locked responses.
