Advanced bio-imaging system |
Prof. Makoto Osanai |
| In order to advance the medical and biological research, spatio-temporal analyses of the biological events are needed. For revealing the mechanisms of biological events, an imaging study has great potentials, since that can monitor simultaneously the responses from a large number of neurons or molecules. However, the existing imaging devices lack the spatio-temporal resolution to measure the dynamics of biological phenomena. To overcome this issue, we conduct the study on development of a high speed and high performance imaging system for the dynamical imaging. We also reveal what can be observed by bio-imaging in the nervous system. With the advancement of this research, it seems possible not only to contribute to the development of basic research in biology, but also to apply the development as an imaging system that can capture various fast phenomena. | |
