在胼胝体压部后缘断面上，中央沟几近消失，大脑外侧面中央沟出现率两侧均为33%。

The central sulcus almost disappeared on the section through the posterior border of splenium of corpus callosum , the appearing rate of the central sulcus on the superolateral surface was 33 % on the both sides .

结果：各组大鼠大脑表面的脑沟回形态正常，冠状切面上弓形隆起的海马大小形态正常，未见明显的萎缩变小。

RESULTS : Normal form of sulci and gyri was observed on the surface of cerebrum , and the size and form of hippocampus with arcuate eminence on the coronal cut were also normal , and there was no obvious atrophy in rats of all groups .

针对大脑皮层表面最大主曲率从脑沟到脑回由小变大，由负变正的分布规律，提出了一种最大主曲率爬山法来对大脑皮层脑沟盆地进行分割。

According to distribution patterns of the maximum principal curvatures changing from small to large , from negative to positive , this paper proposed a maximum principal curvature hill climbing method for the sulcal basins segmentation of the cortical surface .
