| Research Abstract |
We have investigated the design principle of neuronal mechanisms for social adaptation in animals, by focusing on how animals determine their behavior depending on previous social experiments. We focused on cricket agonistic behavior that is released by cuticle pheromones. We are to reveal behavioral and physiological aspects of socially adaptive behaviors. Nitric oxide system and octopamine system in the central nervous system could mediate aggressive behavior of the crickets. Based on our experimental results, we establish dynamic behavior models and neurophysiological models. We found one of important structure that maintains social adaptive behaviors, that is multiple feedback structure which is composed of feedback loop in nervous systems and through social interactions.
