Lateral geniculate nucleus (LGN)

The LGN gets optic information from the optic tract, and sends it to the visual cortex.

The LGN consists of six layers. Information from the eye on the other side goes to layers 1, 4 and 6, and the information from the eye on the same side to layers 2, 3 and 5.

Layer 1 and 2 receive magnocellular input, layers 3 to 6 parvocellular.
