====== Medial geniculate nucleus ====== {{ ::cerebral_peduncle.jpg?500|}} 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 [[neuron]]s. It is thought that the MGB influences the direction and maintenance of attention.
