| Outline of Final Research Achievements |
We previously identified two groups of genes highly expressed in the primate neocortex: One group of the genes are high the primary visual cortex (V1) and the other group of the genes are high in association areas. The comparative analysis among several representative primate species indicate the area-selective expression and activity dependent expression can be separated each other. In this study, we wanted to identify the molecular mechanisms responsible such a segregation. We found that the promoter region of association area selective genes are highly methylated while the methylation of the V-selective genes are low. We then proved that MBD4 positively controls the high expression of association area selective genes. To understand the molecular mechanisms that control the activity dependent expression of V1-selective genes a light inducible gene expression system in marmoset V1 using immediate early genes and confirm the existence of the ocular dominance column in the marmoset V1.
