Draw a picture of and describe the cells of the human retina. Be sure to include current beliefs
concerning the function of each type of retinal cell. Hint – there are 5 major categories, but one
of those categories – the category of receptors – has 4 distinct cell types.
Describe the two major visual “streams” – the “where” and the “what” streams, beginning with
the retina and ending with the lobe of the cortex at which each “stream ends. Describe the
results of one study which illustrated the differences between them.
We have a dual-receptor visual system – rods and cones. Describe the major differences between
the two receptor types. Describe why we might have a dual-receptor visual system.
Describe how the systems differ, including the individual receptor differences, differences in
convergence ratios between the two receptor systems, and differences in locations of the two
systems. Include figures where appropriate to illustrate your points.
Describe two “modules” found in the brain. Tell what the neurons in each module primarily
respond to. Describe where the module is. Say what “stream” the module is likely part of. For
this response, do not use either of the two “streams” referred to above as a “module”.
