Probability map of bundle lh_CMF-PrC_1 (atlas of superficial white matter fibre bundles, version 2018)

This data contains the probability map of a short fibre bundle connecting the left hemisphere Caudal Middle Frontal and Precentral regions of the Desikan-Killiany atlas, in the MNI ICBM152 reference brain. This bundle was identified using a hybrid approach, incorporating anatomical information (from cortical regions of interest) and fibre shape (fibre clustering), from the tractography datasets of 78 subjects in the Neurospin’s ARCHI database. The map shows the probability of finding a fibre belonging to the bundle in each voxel of the reference brain. The maximum probability corresponds to the voxels with the highest number of putative fibres going through.

本数据集包含基于MNI ICBM152标准脑构建的、连接德斯卡安-基利亚尼图谱（Desikan-Killiany Atlas）左侧半球尾侧中额叶与中央前回区域的短纤维束概率图。该纤维束采用混合方法识别，融合了解剖学信息（源自感兴趣皮层区域）与纤维形态特征（纤维聚类），所用数据来自Neurospin的ARCHI数据库中78名受试者的纤维束追踪（tractography）数据集。该概率图展示了在标准脑的每个体素（voxel）中，存在属于该纤维束的纤维的概率，其中概率最大值对应经过该体素的推定纤维数量最多的区域。
