<para id="fs-idp164837360">Once in the brain, visual information is processed in several places, and its routes reflect the complexity and importance of visual information to humans and other animals. One route takes the signals to the thalamus, which serves as the routing station for all incoming sensory impulses except olfaction. In the thalamus, the magnocellular and parvocellular distinctions remain intact, and there are different layers of the thalamus dedicated to each. When visual signals leave the thalamus, they travel to the primary visual cortex at the rear of the brain. From the visual cortex, the visual signals travel in two directions. One stream that projects to the parietal lobe, in the side of the brain, carries magnocellular (“where”) information. A second stream projects to the temporal lobe and carries both magnocellular (“where”) and parvocellular (“what”) information.</para>
<para id="fs-idp5649760">Another important visual route is a pathway from the retina to the <term id="term-00015">superior colliculus</term> in the midbrain, where eye movements are coordinated and integrated with auditory information. Finally, there is the pathway from the retina to the <term id="term-00016">suprachiasmatic nucleus</term> (SCN) of the hypothalamus. The SCN is a cluster of cells that is considered to be the body’s internal clock, which controls our <term id="term-00017">circadian</term> (day-long) cycle. The SCN sends information to the pineal gland, which is important in sleep/wake patterns and annual cycles.</para>
