Final answer:
Visual processing starts in the retina, where visual signals are processed by cones, rods, bipolar cells, and ganglion cells before being transmitted via the optic nerve to the brain for further interpretation in the occipital lobe.
Step-by-step explanation:
The visual processing of information begins in the retina of the eye, before the information reaches the brain. Within the retina, visual signals leave the cones and rods, travel to the bipolar cells, and then to the ganglion cells. It is at this stage that a significant amount of processing occurs. The axons from the ganglion cells come together to form the optic nerve, which transmits the processed information to the brain. Once the visual information passes through the optic nerve and reaches the brain, it is sent to the occipital lobe in the cerebral cortex, which is responsible for further processing and interpreting these signals into images.
Therefore, the correct answer to the question "Where does some visual processing occur before information reaches the brain?" is a) Retina.
