Question

Quizplus · Accepted Answer

At the optic chiasm, axons from the medial (inner) halves of each retina cross to the opposite side of the brain. This means that visual information from the left side of each eye is sent to the right side of the brain, and vice versa. Axons from the lateral (outer) halves of each retina do not cross and remain on the same side of the brain.
