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.
在对解剖学文献进行综述的指导下，人类大脑皮质表面的36条脑沟被确定为同源脑沟。由2名独立观察者对从20名正常志愿者大脑的磁共振成像扫描重建的三维图像上这些脑沟的可见性进行评估。那些被发现可重复识别的脑沟被用于定义皮质表面周围的24个标志点。计算了24个标志点测量的观察者间和观察者内变异性。这些可靠可重复的标志点可用于详细的形态计量分析，并且可能被证明有助于分析癫痫等病症患者疑似大脑皮质结构异常的情况。
