| Outline of Final Research Achievements |
Sex differentiation of the central nervous system in Drosophila is controlled by the function of genes named fruitless (fru) and doublesex (dsx). Sexually dimorphic neural circuitry plays an important role in the execution of courtship and aggression. In this study, we focused on the dsx-expressing pC1 neurons. These neurons can be divided into two groups based on the presence or absence of fru expression. Using the activity manipulation experiments, we revealed that fru-positive subset of pC1 neurons were responsible for commanding courtship behavior, on the other hands, fru-negative subset of pC1 neurons were the commanding neurons for aggressive behavior.
