Visual field: what is visual at any moment. Light from right half of visual field strikes left half of each retina + vice versa. Left half of each retina connects to left hemisphere + vice versa. Optic chiasm: area where axons from each eye cross to the opposite side of the brain. Epilepsy: condition characterized by repeated episodes of excessive synchronized neural activity.
