Document Summary
Dalmatian dog once seen it; easier to notice if look again. Lateral occipital complex (loc) specialized for perceiving or recognizing objects of many kinds. Extrastriate body area (eba): processing bodies (not head) V5 emotion perception, v4 colour perception. Ventral stream processes what information recognition medial temporal region including hippocampus that has to do with memory. Broad generalization: many cross connections between the two streams, feedback as well as feedforward. Part 1: middle vision putting things together gestalt laws, parallel processing, figure-ground. Part 2: high level vision identifying objects picasso and rbc, smart templates.
