| 研究実績の概要 |
For the FY2022, we have scanned 10 more healthy volunteers, completing the MRI scans of all 20 healthy controls. All participants underwent two imaging sessions, about one month apart. Acquired MRI data includes structural T1 MRI data, an hour of resting state functional MRI data, and diffusion-weighted MRI data. Additionally, we have also acquired the MRI data from patients with essential tremor. Preliminary analysis of the acquired datasets from healthy controls have shown that the reliability of the whole-brain FCOR map exhibited an initial rapid increase as more volumes are incorporated into the analysis. With more volumes added, the reliability measure later plateaus suggesting an upper limit to the reliability as well as an optimal number of volumes to achieve this limit. We have also started the analysis of the data from patients with essential tremor. This will be completed in FY2023.

2: おおむね順調に進展している
理由
The implementation of the project in the second year was progressing smoothly as planned. With all the data acquired, we have started the full analysis, which we plan to complete in FY2023.
|
| 今後の研究の推進方策 |
For the FY2023, we will complete the full analysis of the acquired MRI data. The results of the analysis will be presented in upcoming domestic and international conferences and will be organized into a manuscript to be submitted for possible publication in international journals.
|
| 次年度使用額が生じた理由 |
The remaining amount will be used for the promotion of research findings, including presentations in domestic conferences and payment for publications.
