medial geniculate body

Medial geniculate nucleus, or medial geniculate body, a subnucleus of the thalamus in the brain.

The medial geniculate body (MGB) is the output connection from inferior colliculus and the last subcortical way station.

The inferior colliculus, involved in the sense of hearing sends its inferior brachium to the medial geniculate body of the diencephalon.

In 1822, Friedrich Burdach distinguished between the lateral and medial geniculate bodies, as well as named the cingular gyrus.

Thalamocortical axons project primarily from the Medial geniculate Body (MGB) via sublenticular region of the internal capsule and terminate in an organized topographic manner in the transverse temporal gyri of Heschl.

The evoked potential is generated in the cochlea, goes through the cochlear nerve, through the cochlear nucleus, superior olivary complex, lateral lemniscus, to the inferior colliculus in the midbrain, on to the medial geniculate body, and finally to the cortex.

The brachium of superior colliculus (or superior brachium) extends laterally from the superior colliculus, and, passing between the pulvinar and medial geniculate body, is partly continued into an eminence called the lateral geniculate body, and partly into the optic tract.

Occupying the posterior part of the commissure of the optic chiasma is a strand of fibers, the Ventral supraoptic decussation (commissure of Gudden, Gudden's inferior commissure), which is not derived from the optic nerves; it forms a connecting link between the medial geniculate bodies.
