Systematic understanding of the neural mechanisms underlying emergence of adaptive behavior

研究の背景 Background


Animals do not always show the same response to the same stimuli. They usually alter their behaviors in order to respond to the demands of changing circumstances. How do they sense changing environment, how do they process and integrate sensory information in the brain, and how do they produce motor control signals in the brain to emerge adaptive behavior? In order to elucidate these questions, we need to understand the meaning of the environment for the focused individuals. Then we elucidate design principle of the brain. This issue must be common interest between biologist and robotics engineers.

研究の目標 Outcome


The main goal of the research is to understand how animals alter their behaviors in order to respond to the demands of changing circumstances. In order to understand neuronal mechanisms underlying adaptive behaviour, we focus on aggressive behaviour in insects. Insects provide us great model system to elucidate design principle of brain. We perform physiological experiments and then using the results, build dynamic system model to explain the biological functions and then simulate the models. This synthetic process accelerates systematic understanding the design principle of the brain that emerge real time adaptability in changing environment.
