Structure. This is the term for the primary visual cortex, V1, or Brodmannâs area 17. The area encompasses the medial surface and a small lateral surface of the occipital lobe, and is within the calcarine sulcus. It is located at the most posterior portion of the cerebral hemisphere.
The vast majority of the nerve fibres in the optic tract project to the lateral geniculate nucleus (LGN) in the dorsal part of the thalamus. The LGN is the main relay in the pathway to the primary visual cortex. The projection from the LGN to the visual cortex is called the optic radiation. Because damage at any point along the pathway from the retina to the cortex results in some degree of blindness, this is clearly the pathway through which conscious visual perception takes place in human beings.
