Our research is guided by the hypothesis that brain regulation of behavior can be understood at the molecular level. This requires an understanding of the function of networks that regulate behaviors and then an analysis of appropriate brain areas at the molecular level. Due to the methodological development in neuroscience, we have network analysis technologies that can be used to elucidate the pattern of brain activity that correlates with behavioral elements, and we can also use genetic methods to selectively manipulate neuronal activities. Neurons that are key in a given behavior are analyzed at the molecular level using RNA sequencing.In our research, we primarily examine social behaviors. These are complex behaviors, involving multimodal processing of stimuli from conspecifics and also generally complex responses.
