Document Summary
Some ventral stream areas: lateral occipital complex (loc) Specialized for perceiving and recognizing objects of any kind: parahippocampal place area (ppa) Specialized for perceiving and recognizing scenery and locations: fusiform face area (ffa) Specialized for perceiving and recognizing faces: extrastriate body area (eba) Dorsal stream (green region) processes where, how information (how you want to use it in terms of acting upon it: fast but colorblind (chapter 8) Ventral stream (purple region) processes what information: recognizing objects, faces, bodies, etc. 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. Middle vision combines features into objects: the result is object perception. Object recognition means we match a perceived object representation to a representation encoded in memory.
