Document Summary

Jane goodall recognize faces of chimps, but not humans. Something very disinct about our visual system and it"s ability to recognize human faces, separate substructure for this funcion. Fusiform face region (ffr) region only lights up when people are presented with a human face. Recognizing an object - the lateral occipital complex (loc) becomes acivated. When recognizing a face the ventral stream is sill acivated, fusiform face region (ffr) Both in the ventral stream, however they are disinctly separate. Bilateral lesions, afecing both loc and ffr ventral visual pathway. One person who demonstrates a certain level of impairment, and another individual that demonstrated the same but opposite level of impairment. Individuals who have lesions in their dorsal visual pathway (bilateral) opic ataxia. Cannot use vision to control their acions, severe misreaching deicit when reaching for an object. Perform acion without vision (closed eyes) no longer rely on their visual system to control acion; result acion is signiicantly improved.
