本研究提出了一种跨东西方人群的白质图谱，用于同时进行白质映射，并创建了大规模协调的dMRI数据集，以促进对不同文化背景脑差异的研究。

摘要：

研究不同东方和西方人群之间的脑差异为理解潜在的文化和遗传因素对认知和心理健康的影响提供了关键见解。扩散磁共振成像（dMRI）束追踪是评估不同人群中白质（WM）连接和脑组织微观结构的重要工具。然而，由于缺乏跨人群白质图谱和dMRI数据的大地区特异性变异性，对东方和西方人群之间白质纤维束的全面研究面临挑战。本研究提出了一种dMRI束追踪图谱，即东西白质图谱，用于同时进行东方和西方人群的白质映射，并基于人类连接组计划和中国人类连接组计划创建了一个大规模、协调的dMRI数据集（n=306）。经过筛选的白质图谱，以及包含协调的dMRI数据、全脑束追踪数据、分割的白质纤维束及其扩散测量的受试者特定数据均已公开发布。该资源为探索不同文化背景下的脑共性与差异提供了有价值的补充。

英文摘要：

The study of brain differences across Eastern and Western populations provides vital insights for understanding potential cultural and genetic influences on cognition and mental health. Diffusion MRI (dMRI) tractography is an important tool in assessing white matter (WM) connectivity and brain tissue microstructure across different populations. However, a comprehensive investigation into WM fiber tracts between Eastern and Western populations is challenged due to the lack of a cross-population WM atlas and the large site-specific variability of dMRI data. This study presents a dMRI tractography atlas, namely the East-West WM Atlas, for concurrent WM mapping between Eastern and Western populations and creates a large, harmonized dMRI dataset (n=306) based on the Human Connectome Project and the Chinese Human Connectome Project. The curated WM atlas, as well as subject-specific data including the harmonized dMRI data, the whole brain tractography data, and parcellated WM fiber tracts and their diffusion measures, are publicly released. This resource is a valuable addition to facilitating the exploration of brain commonalities and differences across diverse cultural backgrounds.
