Also known as the striate cortex, or simply V1, the primary visual cortex is located in the most posterior portion of the brain's occipital lobe. In fact, a large part of the primary visual cortex cannot be seen from the outside of the brain, because this cortex lies on either side of the calcarine fissure.he 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.
The occipital lobe is located at the lower central back of the brain. It is considered as the primary center for processing visual stimuli. This lobe is also involved in color and movement discrimination, and visuospatial processing. Any significant trauma at the back of the head can cause subtle changes in the visual-perception area.
