The rat's visual field is represented on the cortex of each cerebral hemisphere within a primary visual area, visual field to the rat's right side upon the left hemisphere, and vice versa. The pattern of the representation has been determined electrophysiologically. The part of the visual field commanded by both eyes together, which is ahead of the animal, secures a larger representation upon the cortex in proportion to its size than the rest of the field, which is commanded by only one eye. There is evidence that a second smaller representation exists immediately lateral to the primary area.
