- Results In all subjects,99 cases of central sulcus were well identified and the thickness of precentral gyri was bigger than that of postcentral gyri. 结果明确判定中央沟位置的99例;中央前回的厚度大于中央后回的99例;额上沟和中央前沟相交的76例;中央前回与中央后回厚度之比左侧大脑半球为1.;65;右侧大脑半球为1
- Purpose Significance to study of the central sulcus,precentral and postcentral gyri by MR imaging,to determine its location for application of the clinic. 目的通过使用磁共振影像技术来研究中央沟及其相邻解剖结构在影像中的特征性表现。
- Localization of pre-and postcentral gyri on sagittal sections 中央前、后回在矢状断面上的定位

- Results:Activations follwing motor tasks localized to the HRA area and the postcentral gyrus and the supplementary motor area(SMA)and the prefrontal area as well as the parietal area. 结果:8例患者运动激发后在手运动区(HRA)、辅助运动区(SMA)、中央后回、额前区、顶叶等区域见活动。
- postcentral gyri 中央后回

- The surface of cerebrum is increased by many gyri. 大脑表面由脑回的增多而增大。
- The gyri are flattened from cerebral swelling. 静脉性梗塞区别于动脉性梗塞的主要特点是静脉窦及皮层血管的扩张和血栓形成,通常可伴有脑表静脉周围的蛛网膜下腔出血,有时还可伴有大面积的脑出血或硬膜下出血。

- postcentral gyrus 中心后回,中央后回
- The level of the NAA/Cr ratios in ALS patients was lower than that of the normal controls in the right cerebral peduncle, left anterior of the post limb of internal capsule, and left postcentral gyrus; 与性别、年龄相当的正常人相比;ALS病人的NAA/Cr比值在右侧大脑脚区、左侧内囊后肢前部及左侧中央后回处显著降低(P<0.;05);
- The gyri are narrowed and the sulci widened toward to frontal pole. 脑回变窄,脑沟向着前端变宽。
- 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。
- If so, thick regions (such as the deep layers of gyri) should contain fewer neurons than thin regions of the cortex. 若是如此,较厚的区域(像是脑回底部细胞层)的细胞数会少于较薄的区域。
