What do cones do in the eyes?
|
Cones provide color vision, high visual acuity, and ability to see in bright illumination.
|
|
What do rods do in the eyes?
|
Rods provide the sensitivity that allows vision in dim illumination.
|
|
Where are rods and cones located in the eyes?
|
The retina
|
|
What are the two types of photoreceptor cells in the retina?
|

|
Why do objects appear colored?
|
Objects appear colored because their pigments absorb some wavelengths from white light and reflect others.
|
|
How do we experience different colors?
|
We experience different wavelengths of light as different colors.
|
|
What is the Trichromatic Theory of Color Vision?
|
This theory, derived from the three-primaries law, holds that we have three types of receptors, each most responsive to a particular range of wavelengths.
|
|
What is the Opponent-Process Theory of Color Vision?
|
This theory, derived from the law of complementarity, holds that physiological units involved in color vision are affected in opposite ways (excited or inhibited) by complementary wavelengths.
|
|
What are neural circuits?
|
Neurons that connect together in networks.
|
|
Why is there a blindspot in your vision?
|
Within your eye there is a spot where there are no receptors due to the optic nerve being located there.
