人类大脑皮层的表面是一个高度折叠的薄片，其大部分表面积被掩埋在褶皱中。因此，对于计算和可视化目的来说，这是一个困难的领域。因此，我们设计了一套程序来修改皮质表面的表示，以(I)将其充气，以便隐藏在脑沟内的活动可以被可视化，(Ii)切割并展平整个半球，以及(Iii)将半球转换为简单的可参数表面，例如球体，以建立基于表面的坐标系。(C)1999年学术出版社。
The surface of the human cerebral cortex is a highly folded sheet with the majority of its surface area buried within folds. As such, it is a difficult domain for computational as well as visualization purposes. We have therefore designed a set of procedures for modifying the representation of the cortical surface to (i) inflate it so that activity buried inside sulci may be visualized, (ii) cut and flatten an entire hemisphere, and (iii) transform a hemisphere into a simple parameterizable surface such as a sphere for the purpose of establishing a surface-based coordinate system.
