Probability map of bundle lh_IP-MT_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 Inferior Parietal and Middle Temporal 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Desikan-Killiany图谱（Desikan-Killiany atlas）中连接左侧半球下顶叶（Inferior Parietal）与颞中回（Middle Temporal）区域的短纤维束概率图，其空间基准为MNI ICBM152标准脑。该纤维束通过混合识别方法得到，该方法整合了解剖学信息（取自感兴趣皮层区域）与纤维形态特征（纤维聚类，fibre clustering），数据来源于Neurospin的ARCHI数据库中78名被试的纤维束追踪（tractography）数据集。本概率图展示了标准脑的每个体素内存在归属该纤维束的纤维的概率，其中概率峰值对应经过该体素的推定纤维数量最多的体素。
