We are developing new technologies to visualize biophysical and physiological functions inside the living body, especially to visualize human brain function. Further, we aim to reveal mechanisms of such individual bio-phenomena through animal experiments.
Research and EducationWe are developing new technologies to visualize biophysical and physiological functions inside the living body. In vivo molecular imaging, an important technique in the post-genome strategy, has the potential to visualize the dynamics of individual bio-phenomena processes in cells, organs as well as in the living body. We aim to reveal mechanisms of such individual bio-phenomena in the living body through bio-imaging using MRI, Near-IR optical imaging and electrophysiological techniques.
