| 研究開始時の研究の概要 |
The research focus is to:
1. Establish 3-dimensional microscopy using novel deep ultraviolet fluorescence microscopy for volumetric analysis of brain structures in normal and diseased models
2. Develop open microscopy and open data toolkit to be put in the public domain for general purpose use.
|
| 研究実績の概要 |
The purpose of the proposed research was to develop open source microscopy tools for 3D brain imaging using novel light source for fluorescence microscopy in the deep ultraviolet spectrum.
In FY2021, a prototypical fluorescence microscope for automated serial slicing and high resolution widefield block-face imaging across the whole brain or tissue block of interest was successfully developed. A manuscript submitted on the technical aspects is currently in second phase of revision.
In FY2022, the applications for quantitative analysis was carried out on normal mouse brains. The study is running smoothly as expected.

2: おおむね順調に進展している
理由
In FY2022, tools for quantitative analysis of the cytoarchitecture of the mouse brains was developed using the microscope developed. A technical paper is under final phase of revision to be considered for publication. Further applications of functional imaging are under consideration.
|
| 今後の研究の推進方策 |
The plans for the phase3 (FY2023) of the 3-dimensional (3D) fluorescence microscopy for brain imaging are as follows:
In FY2023, the chief focus would be consolidate all 3D microscopy based tools developed using deep ultraviolet microscope to be put into the open domain as the ‘Do-It-Yourself’ 3D microscope for micro-macro analysis so as to enable smaller neuroscience labs with minimal resources to set-up their own version of 3D microscope for a community based approach towards elucidating brain connectivity.
