Document Summary
Thalamus is the brains sensory switchboard, located on top of the brainstem, it. Optic nerves connect to the thalamus in the middle of the brain and the thalamus to the visual cortex. Optic nerve: carries neural impulses from the eye to the brain. Blind spot: point where optic nerve leaves the eye, because there are no receptors cells located here, creates a blind spot. Fovea: central point in the retina around which the eye cones cluster. Subtractive: removes wavelengths, leaving less light than was originally there. Additive: superimposes light, putting more light in the mixture than exists in any one light by itself. Trichromatic theory: human eye has 3 types of cone photoreceptions (red, green, blue) with differing sensitivities to different light wavelengths. Opponent process theory: based on the idea that there are 4 primary colors of vision: red, green, blue, and yellow.
