The brain functions through neural networks. A constructive approach would be useful to reveal the brain's information-processing mechanisms. At first, to create new neural circuits, we established a system to produce a neuronal fiber with a microfluidic device. Next, to perform in vivo calcium imaging, we developed protocols to make rodents (mice) and non-human primates (marmosets) perform movement tasks with the head-fixed condition. In the future, we would like to elucidate the brain's information-processing mechanisms using these techniques.
