Summary
The Lateral Geniculate Nucleus, often abbreviated as the LGN or otherwise known as the lateral geniculate body, is a nucleus located inside the thalamus. This nucleus acts as a sensory relay, taking in visual information from the optic nerve, and sending out this visual information to the primary visual cortex of the brain.
