Medial geniculate nucleus : ウィキペディア英語版 | Medial geniculate nucleus
The medial geniculate nucleus (MGN) or medial geniculate body (MGB) is part of the auditory thalamus and represents the thalamic relay between the inferior colliculus (IC) and the auditory cortex (AC). It is made up of a number of sub-nuclei that are distinguished by their neuronal morphology and density, by their afferent and efferent connections, and by the coding properties of their neurons. It is thought that the MGB influences the direction and maintenance of attention. ==Divisions== The MGB has three major divisions; ventral (VMGB), dorsal (DMGB) and medial (MMGB). Whilst the VMGB is specific to auditory information processing, the DMGB and MMGB also receive information from non-auditory pathways.
