The site of vision formation is the visual center, and is also a group of nerve cells in the cerebral cortex related to the formation of neural vision. Visual formation is mainly caused by light stimulation in the retina in the form of “dots” to make the visual cells excited, and visual information will be transmitted through the bipolar cells, optic cells, horizontal cells and ganglion cells, through the optic nerve to the lateral geniculate body in the form of a “serial” pattern of information, then The visual information is transmitted to the lateral geniculate body via the optic nerve in a “serial” pattern, and then radiated to the different functional areas of the primary visual cortex, and finally integrated in different cortical areas to produce visual information. The visual center is a group of nerve cells in the cerebral cortex related to the formation of neural vision, mainly located in the occipital cortex on both sides of the talonavicular fissure, which is also known as the striate area because of the special structure of the cortex. At the same time, each hemisphere of the visual center is associated with one half of the visual field of both eyes, and total blindness occurs only when both hemispheres of the center are damaged. As a result, the visual center is the main site of vision formation and plays an important role in the visual field of the eye.
