| Outline of Final Research Achievements |
It is necessary to obtain dynamic characteristics for understanding the mechanism of the brain function. To measure the dynamic characterisits, the development of ultra high-speed MRI measurement method which can measure fast signals accompanied by the nerve activity such as nerve current and synapse was required. In this study, we have realized an ultra high-speed MRI measurement that can sample data in a sub-millisecond (0.8 ms). In addition, in order to measure the brain activity signal seen in normal EEG, we also developed a measurement method to improve the measurement sensitivity by sacrificing the measurement speed. By this MRI measurement method, we could detect fast brain signals seen in EEG.
