Occipital Lobe: The occipital lobe is the posterior part of the cerebral cortex. It is primarily concerned with vision. In addition to David Hubel and Torstein Weisel winning the Nobel Prize for their discovery of how the occipital cortex works in 1981, Ragnar Granit, Haldan Keffer Hartline and George Wald won the Nobel Prize in 1967 for elucidating how the retina works.
