Document Summary
Tuesday, october 15, 2013: read the dronkers reading. When he died, the brain showed that there was a lesion around the end of the superior central sulcus. V1 is where the visual cortica areas are, he found that the angular gyrus is right next to the occipital lobe. Visual information comes in from the our parietal areas, the patient had a lesion on the left, so the left parietal region must be the critical area for reading if you cannot read, you cannot write. Damage in the left parietal region = alexia (reading problem) with agraphia (writing problem) Left inferior parietal region is critical for taking visual symbols and giving them meaning. Damage to the left angular gyrus: if he fixated somewhere, he couldn"t see anywhere else. The splenum of the corpus callosum was damaged which enabled the visual cortical areas to talk to each other. Knew that there must be some occipital damage on the left hemisphere.
