Optic nerve
When light reaches the retina of the eye, when the image is created, it moves throughout the brain through the optic nerve. The optic nerve is the second cranial nerve, Damage Optical nerves can prevent information from being sent from the eye to the entire brain. information from the left eye goes to the right hemisphere of the brain and vice versa; this is because the optic nerve crosses the optical chiasm, causing the optic nerve of each eye to send information to thie opposite side of the brain.
Occipital lobe
After information enters from the optic nerve throughout the brain, the information is sent to the occipital lobe, where the view is processed. The occipital lobe is located in the back of the brain, above the cerebellum, and form the center of the visual perception system, according to the Center for Neuro Skills. Each hemisphere has its own occipital lobe; Therefore, each occipital lobe processes information sent to a particular hemisphere. The occipital lobe controls how one looks at a scene, so that damage to this part of the brain can cause vision mismatch, and is problematic in identifying the color or movement of an object.
Visual cortex
The last part of the brain involved in the eye is the visual cortex, where sensory and motor information is integrated with vision. some visual pathways involved. For example, the ventral visual pathway controls how a person identifies an object, while a visual pathway is dorsal control a person's visual-motor response to an object. In other words, the visual cortex allows you to realize that you are looking at a plate, for example, and then allows you to take it.
