Probability map of bundle lh_CMF-PrC_0 (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MNI ICBM152标准脑（MNI ICBM152 reference brain）中，连接德斯坎-基利亚尼图谱（Desikan-Killiany Atlas）左侧半球尾侧额中回与中央前回区域的短纤维束概率图。该纤维束采用混合识别方法：整合感兴趣皮层区的解剖学信息与纤维形态特征（纤维聚类（fibre clustering）），其数据源自Neurospin的ARCHI数据库中78名受试者的纤维束追踪（tractography）数据集。本概率图展示了标准脑各体素（voxel）内存在属于该纤维束的纤维的概率，概率最大值对应穿行该体素的推定纤维数量最多的区域。
