| 研究実績の概要 |
The final year of the project was devoted to the last remaining scans and additional enhancement of the real-time fMRI system. For this, 3 more participants were recruited and scanned, completing the target number of participants.
Additional tools were also developed for the real-time fMRI system. This included an interface for a small humanoid robot that served as a neurofeedback system for imagined movements. In the current implementation, the real-time classification of the generated activation maps during the scan using support vector machine drives the robot’s arm movement. Another was the development of an algorithm using simultaneous EEG-fMRI to increase the temporal resolution of fMRI feedback to sub-second time scale. The feasibility of the algorithm was investigated using several tasks including working memory, semantic memory, and oddball tasks.
Finally, results obtained this year were presented in domestic as well as international conferences. The developed source code for the real-time system was also shared to other research institutes for use in their own real-time fMRI implementation. The results are also being finalized for possible publication.
