由于脑沟回和脑回的复杂性，很难在皮质表面进行功能的可视化和映射。在文献中描述了展开和展平皮质表面以进行可视化和测量的方法。这使得可视化和测量成为可能，但由于缺乏标准的映射技术，跨多个主题的比较仍然很困难。在本文中，我们描述了两种以标准方式将每个皮质半球映射到球体部分的方法。为了量化皮质的几何特征的准确性，脑沟和脑回-被映射到同一位置，分析多个大脑的脑沟对齐，并生成不同脑沟区域的概率图，用于自动标记分割的脑沟区域。(C)2004 Elsevier B. V.保留所有权利。
Visualization and mapping of function on the cortical surface is difficult because of its sulcal and gyral convolutions. Methods to unfold and flatten the cortical surface for visualization and measurement have been described in the literature. This makes visualization and measurement possible, but comparison across multiple subjects is still difficult because of the lack of a standard mapping technique. In this paper, we describe two methods that map each hemisphere of the cortex to a portion of a sphere in a standard way. To quantify how accurately the geometric features of the cortex - i.e., sulci and gyri - are mapped into the same location, sulcal alignment across multiple brains is analyzed, and probabilistic maps for different sulcal regions are generated to be used in automatic labelling of segmented sulcal regions.
