Visual System II
This chapter considers the overall organization of the central visual pathways. Students should know the names of each component of the central visual pathways and be able to identify each component in brain dissections, histological sections, or drawings. We then define how the information from the two eyes is mapped within the central visual pathways and define the retinotopic organization of the pathways. Students should be familiar with how the fibers of the optic nerve decussate at the optic chiasm, and how different parts of the visual field are represented in the optic tract, lateral geniculate nucleus, and cortex. This information is the key to understanding the visual field deficits that result from lesions at particular locations along the central visual pathways.
