| Outline of Final Research Achievements |
Since various regions of the brain are composed of functional units called columnar structures, understanding the molecular mechanisms of column formation is an important research topic in neuroscience. However, the mechanism by which column structures are formed from different cell populations during development is still largely unknown. Using the Drosophila visual center, which has a simple column structure, as a model system, we have elucidated the evolutionarily conserved mechanism of column formation. Specifically, we elucidated the mechanism of column formation by differential cell adhesion between core columnar neurons and repulsive effects between neurons of the same lineage. We also elucidated the molecular mechanism that determines the orientation of the neurons constituting the column.
