- There are two different information pathways in our visual system - The bottoms up pathway is concerned with who or what an object is. It is primarily involved in the raw processing of the sensory information on our eyes. - The top down pathway is concerned with the where an object or a person is located. It uses past information and makes interpretations and understands the context. --- The visual system. Information flows from the retina to the lateral geniculate nucleus through the optic nerve. The lateral geniculate nucleus sends information to the primary visual cortex, which gives rise to two major pathways: the where pathway concerned with where an object or a person is located and the what pathway which is concerned with what an object is or who a person is. - [[Reductionism in Art and Brain Science]]
