Outline of Final Research Achievements

We demonstrated that the visual cortex became to work as a part of the auditory cortex after the blindness. To evaluate the function of visual cortex in blind rats after restoring vision by transducing mVChR1 gene, we recorded the visually evoked potentials with a stimuli of white noise or light. We could still record the auditory response in the visual cortex in rats restored vision, and there is no significance of the recorded responses between in blind and vision-restored rats. These results indicated that the functional change of visual cortex was kept after the vision restoration. We might develop the method to accelerate the brain plasticity.
