- The gyri are narrowed and the sulci widened toward to frontal pole. 脑回变窄，脑沟向着前端变宽。
- precentral gyrus 中央前回,中心前回
- The crests of the gyri are most susceptible to the traumatic forces. 脑回顶部容易受到创伤外力的打击。
- Mainly the gyri are affected with hemorrhage from contusions and lacerations. 脑回挫裂伤引起出血。
- The cerebral atrophy seen here mainly in the frontal and parietal regions is characterized by narrowed gyri and widened sulci. 图示脑萎缩主要发生在额叶和顶骨区域，表现为典型的脑回变窄和脑沟变宽。
- Moreover, in lissencephaly (smooth brain), an absence of gyri and sulci and occasionally ventriculomegaly may be noted. 此外，在无脑回（平滑脑）中，可以看看见缺乏脑沟和脑回，偶尔可见脑室扩大。
