It includes the retina, optic nerve, optic chiasm, optic tract, lateral geniculate nucleus (LGN), optic radiations, and striate cortex (Figure 13-1).

The visual pathway from the eye to the brain

WebbThe retina has two main parts: the macula and the peripheral retina. The macula is a small spot near the center of the retina that provides central vision. It's made up of many tiny cones that sense color and detail in the middle distance. The visual information processed by the macula is sent to the brain via the middle branch of the optic nerve. WebbWithin the layers of the retina, light impulses are changed into electrical signals. Then they are sent through the optic nerve, along the visual pathway, to the occipital cortex at the posterior (back) of the brain. Here, the electrical signals are interpreted or “seen” by the brain as a visual image. Webb1 apr. 2012 · Vision begins with light passing through the cornea, which does about three-quarters of the focusing, and then the lens, which adjusts the focus. Both combine to produce a clear image of the visual world on a sheet of photoreceptors called the retina, which is part of the central nervous system but located at the back of the eye. onn laptop charger tips
