Involvement of the medial geniculate body in prepulse inhibition of acoustic startle
Psychopharmacology, 1999Prepulse inhibition of acoustic startle is the normal reduction in startle response to an intense auditory stimulus when this stimulus is immediately preceded by a weaker prestimulus. Previous studies have shown that several neuroanatomical structures and pathways in the brain are involved in the modulation of prepulse inhibition. In the present study,

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 ...

Maturation of the primary cortical response to stimulation of medial geniculate body
Electroencephalography and Clinical Neurophysiology, 1967Abstract 1. 1. The maturation of the cortical response to electrical stimulation of the MG was investigated in rats and in cats from the first hours after birth until maturation of the animals. 2. 2. In both species this response is present from the first hour after birth.

Subdivisions of the medial geniculate body in the tree shrew (Tupaia glis)
Brain Research, 1975The medial geniculate body of the tree shrew has 3 major divisions which can be identified on the basis of cytoarchitecture. Each of these major divisions can be subdivided further. The present paper describes these divisions and compares them in terms of their patterns of afferent and efferent connections.

Is There Stimulus-Specific Adaptation in the Medial Geniculate Body of the Rat?
2010Neurons in the auditory cortex (AC) show a reduced response to a repeated stimulus, but briefly resume firing if a novel stimulus is presented (Nat Neurosci 6:391-398, 2003). This phenomenon is called stimulus-specific adaptation (SSA). This same study concluded that SSA is absent in the medial geniculate body (MGB), and is therefore a unique feature ...

Neural coding of repetitive clicks in the medial geniculate body of cat
Hearing Research, 1981The activity of 418 medial geniculate body (MGB) units was studied in response to repetitive acoustic pulses in 35 nitrous oxide anaesthetized cats. The proportion of MGB neurons insensitive to repetitive clicks was close to 30%. On the basis of their pattern of discharge, the responsive units were divided into three categories.

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 ...

Neurochemical Organization of the Medial Geniculate Body and Auditory Cortex
2010The auditory, visual, and somatic sensory systems each have a topographic receptor epithelium, multiple central representations of the peripheral mosaic, parallel neural streams serving epicritic processing, vast networks of central connectivity, and a web of intrinsic circuits at all levels of processing.
