lateral geniculate body
medical dictionary

The lateral one of a pair of small oval masses that protrude slightly from the posteroinferior aspects of the thalamus; its main (dorsal) subdivision serves as a processing station in the major pathway from the retina to the cerebral cortex, receiving fibres from the optic tract and giving rise to the geniculocalcarine radiation to the visual cortex in the occipital lobe.

Synonyms: corpus geniculatum laterale, corpus geniculatum externum.
