在回顾解剖学文献的基础上，将人类大脑皮质表面的36个脑沟指定为同源的。由2名独立观察者对20名正常志愿者的大脑进行磁共振成像扫描，并在三维图像上对这些脑沟的可见性进行评估。那些被发现是可重复识别的脑沟被用来定义皮质表面周围的24个标志。计算24个标志点的观察者间和观察者内测量变异性。这些可靠的可重复的标志可用于详细的形态学分析，并可能证明有助于分析可疑的大脑皮层结构异常的患者，如癫痫。
Guided by a review of the anatomical literature, 36 sulci on the human cerebral cortical surface were designated as homologous. These sulci were assessed for visibility on 3-dimensional images reconstructed from magnetic resonance imaging scans of the brains of 20 normal volunteers by 2 independent observers. Those sulci that were found to be reproducibly identifiable were used to define 24 landmarks around the cortical surface. The interobserver and intraobserver variabilities of measurement of the 24 landmarks were calculated. These reliably reproducible landmarks can be used for detailed morphometric analysis, and may prove helpful in the analysis of suspected cerebral cortical structured abnormalities in patients with such conditions as epilepsy.
