The visual information from the lateral part of the visual field is processed on the opposite side of the cortex, while information from the middle part of the visual field is processed on the same side of the cortex. This is due to the crossing over of visual information at the optic chiasm, where the nasal (medial) retinal fibers cross over to the opposite side of the brain and the temporal (lateral) retinal fibers continue on the same side of the brain.
