至脑岛外侧份层面时，12点位正好是中央沟，再向外切时，中央沟基本保持该方向不变。

On the section cutting insula , central sulcus locate exactly 12 o'clock direction and outward is ultimately changeless .

结果全部病例均在术中获得安全可靠的麻醉唤醒，清醒状态下脑功能区的定位和最大限度地肿瘤切除，其中6例获得皮层体感诱发电位检测确定中央沟；

Results All cases received safety awake surgery for accurate location of both lesions and eloquent areas and maximal resection of tumors .

结果5例正常扫描均能清楚地显示中央沟、外侧裂等大脑半球的主要沟回。

Results 5 normal cases with surface anatomy scanning showed excellent visualization of the sulci and gyri on the surface of the brain .

结果显示：扣带沟缘支和外侧沟后升支是识别中央沟的标志，若出现壁间回则更易识别中央沟；

The results showed that marginal ramus of cingulate sulcus and posterior ascending ramus of lateral sulcus are the landmarks for recognition of central sulcus .

结论磁共振成像技术是观察中央沟及相邻解剖结构最为有效的影像学方法，对于判断中央沟区病变的定位有重要的价值。

Conclusion MR imaging is the best method to show central sulci and its adjacent structures and has definite values in locating the lesions of central sulci .

病变部位分布如下：滑车中央沟47处，中央沟内侧斜面68处，外侧斜面57处，股骨内髁85处，股骨外髁70处。

Lesions distributed as follows : block 47 the central sulcus , central sulcus inside slant 68 , the outer slope 57 , femoral condyle 85 , femoral condyle 70 .

对这些影像学进行分析的第一步工作就是对他们的共同解剖学结构进行校准，例如将运动皮层与躯体感觉皮层分离开的中央沟。

The first step in analyzing these images is to align their common anatomical structures , such as the " central Sulcus ," a fold that separates the motor cortex from the somatosensory cortex .
