Probability map of bundle rh_RMF-SF_0 (atlas of superficial white matter fibre bundles, version 2018)

This data contains the probability map of a short fibre bundle connecting the right hemisphere Rostral Middle Frontal 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.

该数据包含Desikan-Killiany脑图谱中右半球喙部中额叶与上额叶区域之间短纤维束的概率图，以MNI ICBM152标准脑模板为参考。此纤维束通过混合方法识别，结合了来自皮质感兴趣区的解剖学信息与纤维形状（纤维聚类），数据来源于Neurospin的ARCHI数据库中78名受试者的纤维束成像数据集。该图显示了在标准脑模板的每个体素（voxel）中发现属于该纤维束的纤维的概率。最大概率对应于有最多潜在纤维穿过的体素。
