1 Tissue, Total RNA, Human Disease, Alzheimer's Disease, Precentral Gyrus.

2 Conclusion:The precentral sulcus appears on the 1 2 sections that the lenticular nucleus and anterior limb of internal capsule appear but the anterior commissure and dorsal thalamus doesn't appear.

3 Objective:To investigate the accurate localization of the precentral sulcus in adults.

4 The posterior frontal vein, precentral vein, central vein,[] postcentral vein and anterior parietal vein join the middle segment of superior sagittal sinus.

5 Reconstruction of bilateral CST in the control group, precentral gyrus to internal capsule and continued to pontine and medulla oblongata, and concordance was good in each.

6 Inhibited areas: bilaterally in upper middle precentral gyrus and postcentral gyrus, superior parietal lobule, inferior parietal lobule and prefrontal cortex.

7 The locations of the DCES were concordant with those of the precentral gyrus judged by the CSEP in 33 cases, and CSEP was atypical but DCES positive in 5 cases.

8 MRI of the brain confirmed the presence of a lesion of the right precentral gyrus.

9 In the control group, signal increases areas were demonstrated in superior temporal gyri , precentral gyri , cingulate gyri , thalamus, insula and cerebellum.

10 Some veins of the basal veins, the internal occipital veins and the precentral cerebellar veins were very wide.
