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 ...

Anatomy of the rat medial geniculate body: II. Dendritic morphology
Journal of Comparative Neurology, 1990AbstractThe medial geniculate body (MGB) of the rat was studied with Golgi methods to determine the distribution of neurons identified by dendritic morphology. These findings were compared with major divisions and constituent nuclei established by somatic and fiber architectonics, and by connections with temporal neocortex (Clerici et al.: Society of ...

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 ...

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.

The Medial Geniculate Body and Associated Thalamic Cell Groups: Behavioral Studies
Brain, Behavior and Evolution, 1972Deficits in auditory discrimination aredescribed after cortical ablations that produce thalamic degeneration that differs in amount and in locus.

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.

Medial Geniculate Body Unit Responses to Cat Cries
1988Participation of different auditory pathways for various kinds of auditory information processing is suggested by a variety of behavioral and anatomical data. Behavioral testing procedures indicate that bilateral lesions of the primary auditory cortex cause no loss in discrimination of temporal sequencing of auditory stimuli (summarized in Colavita ...

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.
