Question 2
In visual sensation, roughly 120 million bits of information are processed by the visual receptors (rods and cones). However, only about 1 million bits of information are transmitted to the brain via the optic nerve.
By what mechanism does this information compression take place?

b) Some bipolar cells block the transmission of redundant information.
c) Only receptors in the fovea can activate bipolar cells.
d) The optic nerve can only be activated by some bipolar cells.
