Probability map of bundle lh_RAC-SF_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 Rostral Anterior Cingulate and Superior Frontal 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Desikan-Killiany脑图谱（Desikan-Killiany atlas）左侧半球喙部前扣带回与额上回区域的短纤维束概率图谱。该纤维束通过整合感兴趣皮层区解剖学信息与纤维形态特征（纤维聚类，fibre clustering）的混合方法识别，数据来源于Neurospin的ARCHI数据库（Neurospin’s ARCHI database）中78名被试的纤维束追踪数据集。该图谱展示了标准脑每个体素内存在归属该纤维束的神经纤维的概率，概率最大值对应走行通过推定纤维数量最多的体素。
