|
Retina |
the part of the eye that converts the electromagnetic energy of light to electrical impulses for transmission to the brain |
|
|
Rods |
Thin,cylindrical receptor cells in the retina that are highly sensative to light |
|
|
Cones |
Cone-shaped,light sensative receptor cells in the retina that are responsible for sharp focus and color perception, particularly in bright light |
|
|
optic nerve |
a bundle of ganglion axons that carry visual information to the brain |
|
|
Feature detection |
the activation of neurons in the cortex by visual stimuli or specific shapes or patterns |
|
|
Trichromatic theory of color vision |
the theory that there are three kinds of cones in the retina, each of which responds primarily to a specific range of wavelenghts. |
|
|
Opponent process theory of color vision |
The theory that receptor cells for color are linked in pairs, working in opposition to each other. |

3. A woman with blue eyes could be described as having blue pigments in her? |
iris |
|
|
4.what is the process by which the thickness of the lens is changed in order to focus light properly? |
accomodation |
|
|
5. the proper sequence of structure that light passes through in the eye is the __,___,___, and ___ |
cornea,pupil,lens, retina |
|
|
6A. Rods Cones |
Rods : Used for dim light, largely insensitve to color Cones: Detect color, good in bright light |
|
|
7. ___ theory states that there are three types of cones in the retina, each of which responds primarily to a different color |
Trichromatic |
|
|
RETHINK If the eye had a second lens that "unreversed" the image hitting the retina , do you think there would be changes in the way people perceive the world? |
??? |
