Draw the binocular visual pathways, from retina to lateral geniculate nucleus to primary visual (striate) cortex, with special regard to the partial decussation at the optic chiasm and its consequences for the visual field representation at higher levels of the pathway.
Explain how specific visual field defects can arise from lesions at different sites, including the optic nerve, chiasm and radiation, and at different locations within striate cortex. Give examples of how some of these defects may arise.
Outline briefly the basic processes of visual integration occurring at different levels of the visual pathway, and how these relate to interpretation of the retinal image.
Explain briefly the concept of functional specialization and the clinical effects of focal extrastriate lesions, especially in relation to the visual perception of colour and motion.
Describe the afferent and efferent pathways underlying the pupillary light reflexes (direct and consensual) and the near reflex.
Outline briefly the circadian visual system and indicate its significance
