人类大脑皮层沟回结构的精确定位对于解释形态功能数据是重要的，但需要解剖学专业知识，并且由于大脑的几何复杂性而耗时。开发的软件自动识别脑沟回结构已大大改善的技术，提供拓扑正确的重建允许膨胀的意见，人类大脑的结果。在这里，我们描述了一个完整的包裹皮质表面使用标准的国际公认的命名和标准。此封装在FreeSurfer软件包中提供。首先，计算机辅助的手工分割将每个顶点分类为脑沟或脑回，然后将其细分为每个半球的74个标签。12个数据集被用来开发规则和算法（在这里报告），产生符合解剖规则的标签，以及自动计算分割。最终的包裹用于构建自动标记整个大脑皮质的图谱。该图谱用于标记另外12个数据集，发现这些数据集与手动标签具有良好的一致性。本文提出了一种精确定义的方法自动标记皮质表面的标准术语。
Precise localization of sulco-gyral structures of the human cerebral cortex is important for the interpretation of morpho-functional data, but requires anatomical expertise and is time consuming because of the brain s geometric complexity. Software developed to automatically identify sulco-gyral structures has improved substantially as a result of techniques providing topologically-correct reconstructions permitting inflated views of the human brain. Here we describe a complete parcellation of the cortical surface using standard internationally-accepted nomenclature and criteria. This parcellation is available in the FreeSurfer package. First, a computer-assisted hand parcellation classified each vertex as sulcal or gyral, and these were then subparcellated into 74 labels per hemisphere. Twelve datasets were used to develop rules and algorithms (reported here) that produced labels consistent with anatomical rules as well as automated computational parcellation. The final parcellation was used to build an atlas for automatically labeling the whole cerebral cortex. This atlas was used to label an additional 12 datasets, which were found to have good concordance with manual labels. This paper presents a precisely-defined method for automatically labeling the cortical surface in standard terminology.
