| Outline of Final Research Achievements |
To clarify the mechanism of the neural circuit reorganization, we have established connectomics analysis of visual cortex. After monocular deprivation, the neurons in the visual cortex were more received from open eye input. As a result of having immunohistochemically analyzed using c-Fos, FosB and CREB, these activity dependence inducted proteins were resulted to detect the changes of ocular dominance plasticity. Using connectomics analysis, synaptic connections were cyclopedically analyzed in layer IV of visual cortex. As a result, we detected that first the synapses received from deprived eye input were reduced, next the synapses received from opened eye input were increased.
