| Outline of Final Research Achievements |
We have developed a new method to classify brain regions rationally. We obtain Raman spectral information for each pixel on the brain slices of songbirds. Using this spectral information, regions with similar spectra were extracted and mapped. As a result, myelin wrapped nerve fibers and several neurons with neurotransmitters (serotonin, dopamine and glutamate) could be detected without staining. As a method to rationally determine the brain region boundary, we attempted Voronoi division using nuclear position. As a result, we succeeded to divide the entire coronal section of the bird's brain into Voronoi units. By using this division method together with unstained imaging, it is possible to construct a brain draft map at high speed.
