Optical bioimaging and optogenetics have recently made it possible to control brain functions. However, these methods have limitations, such as the inability to regulate neural activity with a high spatiotemporal resolution. To address this limitation, we have developed microscope for biological applications by integrating optogenetics and digital holographic technology. This provides precise spatiotemporal information about neural activity.
In the central nervous system (CNS), glial cells, originally termed “nervenkitt,” recently focused because of the understanding of their physiological functions. Here, we focused how glial cell regulates the function of neuronal circuits using in vivo two photon microscope. In this research, we visualized neural activity in the motor cortex during motor learning using in vivo two photon microscope to understand the abnormality of neural activity associated with impaired behavior output with myelin dysregulation. We further demonstrate the optogenetic stimulation to compensate the abnormal activity of neural activity to rescue the learning disability.
