Why is the blind spot of the
retina blind?
It is on the border between the
area with rods and the area with
cones.
It is the point where the optic
nerve leaves the retina
and there are no rods or cones.
It is in the shadow of the
pupil.
Activity of the receptors is
silenced by excessive lateral
inhibition.

system, a high degree of
convergence is to a low degree
of neural convergence as

acuity.

sensitivity.
c. black/white is to color vision.
d. all of the above.

retina
a. with the greatest perception of
detail.

of the optic nerve.
c. that falls in the shadow cast by
the pupil.
d. that has only rods, not cones.
