===Optic radiation===
{{Main|Optic radiation}}

The '''optic radiations''', one on each side of the brain, carry information from the thalamic [[lateral geniculate nucleus]] to layer 4 of the [[visual cortex]]. The P layer neurons of the LGN relay to V1 layer 4C β. The M layer neurons relay to V1 layer 4C α. The K layer neurons in the LGN relay to large neurons called blobs in layers 2 and 3 of V1.<ref name=Tov2008 />

There is a direct correspondence from an angular position in the [[visual field]] of the eye, all the way through the optic tract to a nerve position in V1 up to V4, i.e. the primary visual areas. After that, the visual pathway is roughly separated into a [[Two-streams hypothesis|ventral and dorsal pathway]].
