However, the medial portion of each nerve crosses over at the optic chiasm and goes to the medial visual cortex on the other side of the brain (medial right nerve to left medial visual cortex and medial left nerve to right medial visual cortex).Ĭolor vision. The lateral portion of each optic nerve travels from the optic chiasm to the lateral visual cortex on the same side of the brain (that is, the outside of the right nerve to right visual cortex and the outside of the left nerve to the left visual cortex). Visual information proceeds from the eye through optic nerves attached to the retina at the back of each eye the optic nerves meet and then divide at the optic chiasm in the center of the brain (Figure ). ![]() The rods are important for night vision and peripheral vision and have a greater density at the edge of the retina. The cones, in the center (fovea) of the retina, are responsible for color vision, and operate best in intense illumination. Light travels to the eye and passes through the cornea, the pupil (regulated in size by the iris), and the lens and then moves to the retina, where it strikes the photoreceptors for vision, the cones and the rods. The amplitude (wave height) is associated with the sensory experience of brightness the wavelength determines the hue (color) of the light and the wave purity (whether there is more than one type of wave) produces the psychological experience of saturation. The stimulus for vision is light, which travels in waves.
