Question 1

Select the statement below that is not true with regards to the process of light adaptation.
◦ Rhodopsin is uncoupled from light transduction.
◦ Visual acuity is diminished.
◦ Retinal sensitivity decreases.
◦ The activity of rods is reduced by rapid bleaching of rhodopsin.

Question 2

Humans can see several thousand shades of color but have cone photoreceptors that are sensitive to only three (perhaps four) wavelengths of light. What is the best explanation for why we see so many colors?
◦ Shades of color are purely psychological and learned by association with age, infants only seeing in black and white.
◦ Color perception is dependent on the millions of rods as well as cone photoreceptors.
◦ Colors are added and enhanced in the primary visual cortex of the brain.
◦ Color perception is achieved by activation of various combinations between the three cone types.
