| Research Abstract |
In this study, we tried to elucidate molecular basis for evolution of behavior, especially in species-specific learned vocal patterns in songbirds. For the purpose, we focused on the relationship of genes which had species-specific regulation in song system and species-specific song patterns. So far, we performed to construct a molecular phylogenetic tree and extract species-specific song features with a novel song analysis method. Furthermore, we succeeded to elucidate genes which had which had species-specific expression patterns and levels in song system among 10 Asian songbird species using DNA microarray. Now, we are trying to adult adeno-associate virus expression system into songbird brain to over-or down-regulation of genes which are regulated with species-specific manner.
