Document Summary
How does the nervous system solve many different problems at the same time (red truck speeding) Solved by having different neural structures for each function (color, form, motion) But this has created the binding problem - how do we see the world as a whole, not a bunch of little bits. Then our behavior in relation to visual stimulation is mediated by two systems - the dorsal stream and ventral stream. Rods and cones dedicated to some of these visual regions. Layer 4 has 3 sublayers because it is input. Matisse - self portrait - note that the color doesn"t contribute much to the identity of the portrait. Not all primates have all 3 cones, we do. Color and form do not not interfere with each other. Vision for perception - visual agnosia - conscious. Vision for action - visual ataxia - unconscious. You do not have to grasp objects to recognize them.
