Probabilistic cytoarchitectonic map of Area 6v3 (PreCG) (v11.0)

This dataset contains the probabilistic map (PM) of the ventral premotor area (Area 6v3 (PreCG)) of the ventral precentral gyrus of the human brain. As part of the Julich-Brain Atlas (JBA), the area was identified using cytoarchitectonic analysis on cell-body-stained histological sections of 10 human postmortem brains obtained from the body donor program of the University of Düsseldorf. The results of the cytoarchitectonic analysis were then mapped to common brain reference spaces, where each voxel was assigned the probability to belong to Area 6v3 (PreCG). The PM of Area 6v3 (PreCG) is provided in NifTi-1 format for each brain reference space and hemisphere. The JBA relies on a modular, flexible and adaptive framework containing workflows to create the probabilistic brain maps for these structures that was described by [Amunts et al. in 2020](https://doi.org/10.1126/science.abb4588). Note that methodological improvements and integration of new brain structures may lead to small deviations in earlier released datasets.

本数据集包含人类大脑腹侧中央前回的腹侧运动前区（Area 6v3 (PreCG)）的概率图谱（probabilistic map，PM）。作为尤利希脑图谱（Julich-Brain Atlas，JBA）的组成部分，该脑区通过对10例取自杜塞尔多夫大学遗体捐赠项目的人类死后大脑的胞体染色组织切片开展细胞构筑学分析得以定位识别。随后将细胞构筑学分析的结果映射至通用脑参考空间，其中每个体素（voxel）都会被赋予属于Area 6v3 (PreCG)的概率值。针对每种通用脑参考空间与大脑半球，本数据集均以NIfTI-1格式提供该脑区的概率图谱。尤利希脑图谱依托一套模块化、灵活且自适应的框架，该框架包含用于生成此类脑区概率图谱的工作流，相关框架由Amunts等人于2020年发表（https://doi.org/10.1126/science.abb4588）。请注意，方法学改进与新脑结构的整合可能会导致早期发布的数据集出现细微偏差。
