| Outline of Final Research Achievements |
Although the autonomic nervous system has an critical role in the regulation of functions of any organs and in the maintenance of homeostasis, its dynamics remain unclear because of a lack of measurement technology. In this study, we developed a neural micromachine, a neural physical interface with microelectrode array, challenged to measure an electrical activity of each neural fiber in the peripheral nerve and actually recorded cardiac vagal nerve activity from cervical nerve. In addition, we developed genetic multicolor fluorescent imaging of autonomic nervous system to measure its intra-organic activity, and actually visualized the neural ending activity of each neural fiber of muscle sympathetic nerve in vivo by two-photon microscope imaging technology.
