Document Summary
Audio recording started: 1:05 pm wednesday, february 7, 2018: macular degeneration, depriving foveal cortex, extensive central retinal damage, visual field: scotoma/blind in fovea. Use the bottom part of retina to see. Preferred retinal locus -- prl -- blow up letters to read through their peripheral vision: mostly in the bottom, some have it to the left, atypically to the right and above scotoma. Does the deprived cortex reorganize: do not know if this locus fixation is active or passive, fmri experiment. Presented pictures in prl and in the scotoma region. Prl stimuli did not show activation in the above calcarine region as in normal but rather in the foveal confluence given the prl is below the scotoma. Foveal region activation + other regions due to ffa . No foveal activation but other regions foveal and surrounding. Yes in stroke and md: what are the perceptual consequences: elongation.
