Summary
This document describes visual field processing, explaining how the brain interprets visual information. It details the role of optic nerves and the optic chiasm in this process. The summary covers aspects of the path of light rays, and the resulting visual field.

Right side of body controlled by left side, vice versa. How does it work in vision? All right visual field goes to left side of brain; all left visual field goes to right side of brain. Ray of light from the left visual field hits the NASAL side of the left eye and hits the TEMPORAL side of the right eye o Vice Versa for light from the right visual field. Ray of light from the right visual field hits the NASAL side of the right eye and hits the TEMPORAL side of the left eye Optic nerves from each eye networks the electrical signal to the brain and converge from each eye at the optic chiasm and then break off and dig deeper into the brain o Now….all light from the nasal side of both eyes cross to the other side so left nasal info goes to the right side and vice versa. o On the other hand, all axons leading from the temporal side DO NOT CROSS the optic chiasm. o What it effectively does, is the right visual field goes to the left brain and the left visual field goes to the right side of the brain 25
