Posterior portion of the brain's occipital lobe The primary visual cortex is located in the most posterior portion of the brain's occipital lobe.
The image captured by each eye is transmitted to the brain by the optic nerve. This nerve terminates on the cells of the lateral geniculate nucleus, the first relay in the brain's visual pathways. The cells of the lateral geniculate nucleus then project to their main target, 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. LGN neurons project to the primary visual cortex, which is located at the back of the head mostly on the medial side. The primary visual cortex has many names: V1, area 17, & striate cortex. The primary visual cortex lies in the fold of the calcarine sulcus. Describe the structure of primary visual cortex (V1). V1 is a map of the retina composed of a grid (1 mm by 1mm) of hypercolumns.  Each hypercolumn analyses information from one small region of retina.  Adjacent hypercolumns analyze information from adjacent areas The primary (parts of the cortex that receive sensory inputs from the thalamus) visual cortex is also known as V1, V isual area one, and the striate cortex. The extrastriate areas consist of visual areas two (V2), three (V3), four (V4), and five (V5). The visual cortex of the brain is the part of the cerebral cortex responsible for processing visual information. This article addresses the ventral/dorsal model of the visual cortex. Another model for the perceptual/conceptual neuropsychological model of the visual cortex was studied by Raftopolous. From the LGN, visual information is relayed to the visual cortex. Some of the axons in the tract project to the superior colliculi, paired structures located on the roof of the midbrain. The superior colliculi help coordinate rapid movements of the eye toward a target. A total of 6 separate areas in the visual cortex exist: V1, V2, V3, V3a, V4, and V5. The primary visual cortex, or V1, is the first structure in the visual cortex, where the neurons form the LGN synapse. The primary visual cortex, V1, is the koniocortex (sensory type) located in and around the calcarine fissure in the occipital lobe. It is the one that receives information directly from the lateral geniculate nucleus .To this have been added later as many as thirty interconnected (secondary or tertiary) visual areas. Visual area V2 is the second major area in the visual cortex, and first region within the visual association area. It receives strong feedforward connections from V1 and sends strong connections to V3, V4, and V5. 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. 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. Area V1 is located in both hemispheres. V1 in the left hemisphere receives input from the left LGN, and thereby from the left portion of the two retinas, which capture images from the right visual field (Figure 1).  The visual cortex is located in the occipital lobe (one of the four major lobes of the cerebral cortex) which is in turn located at the back of the head or skull. The visual cortex is made up of Brodmann area 17 (the primary visual cortex), and Brodmann areas 18 and 19, the extrastriate cortical areas. The visual cortex of the brain is the part of the cerebral cortex responsible for processing visual information. This article addresses the ventral/dorsal model of the visual cortex. Another model for the perceptual/conceptual neuropsychological model of the visual cortex was studied by Raftopolous. The visual system is the part of the central nervous system which gives organisms the ability to process visual detail, as well as enabling the formation of several non-image photo response functions. The visual system includes the eyes, the connecting pathways through to the visual cortex and other parts of the brain. The illustration shows the mammalian system.
