Document Summary
Cortical visual areas other than v1 (striate cortex) More processing is done for vision in these areas. Slide 13 mapping the visual area around their functions. N. b: v5 = mt (motion, v4 colour, v3 form. Different areas of the brain do specialized tasks. V1 acts as a kind of processor/sorter. Damage to the parietal lobe: stroke leads to visual neglect. 1 side not included in the drawing. You still have normal vision: interested in the spatial layout. Of the present and memories: it is a problem of consciousness/attentions. You see it when it is pointed out. You concentrate so much on one side; you forget the other : optic ataxia. A key symptom of the balint"s syndrome. Problem fixating on 1 stimulus at a time. Hard time orienting objects to fit the slot (e. g. putting a key into a keyhole) Caused by lesions in the parietal lobe. Damage to the temporal lobe: failure of object recognition, associative agnosia.
