Insects have a small brain, but their behavior is highly adaptive. We think that the physical
structure of the interaction networks in a brain affects the brain function, and behavioral processors can be
modeled that are controlled by the structural disposition of the networks. In this research, we investigate
the mechanisms behind intelligent behaviors using a novel system called the bio-machine hybrid system. We
carry out the following experiments: (i) the adaptability of an insect-driven robot is studied, (ii) a cyborg
that includes an insect brain and a mechanical body is used for analyzing dynamic brain systems, and (iii)
a network model is constructed to trigger long-lasting excitation.
