Document Summary

Lecture 6: two streams for visual processing 2/12/18. Damage to v4- achromatopsia grayscale, can"t perceive color. Damage to mt- akinetopsia can"t perceive motion. Damage to ffa- prosopagnosia can"t perceive faces. Yes, amputee reported feeling referred touch, and some report phantom limbs. Yes, neurons that initially responded to amputated limbs reorganized and respond to different inputs. Deprived neurons reorganized to respond to different parts of retina. Stroke patient that had damage to lower right optic radiations neurons reorganized to respond to other areas of retina. What and where? (ungerleider and mishkin study) Reward given for detecting the target object. Monkey is trained to pick the food well next to a cylinder. Using ablation, part of parietal lobe was removed from half the monkeys and part of temporal lobe removed from other half. Removal of temporal lobe tissue problems with object discrimination task (what pathway) Removal of parietal lobe tissue problems with location discrimination task (where pathway)
