|Electrical impulses are sent from the retina, through the optic nerve,
and to the brain.
Nerve fibers connected to the rods and cones come together to form a bundle
called the optic nerve. The optic nerve transmits electrical impulses from the
retina to the brain.
The images "projected" on the retina are actually upside down, and are communicated
to the brain this way. Through a complex process, the brain interprets the images
right side up.
