sulci造句
1. Conlusion:System for localizinggyri and sulci along the low-middle convexity on sagittal MRI, providing an effective and valuable tool for localization. 2. The involved cerebral hemisphere will have enlarged sulci if the cerebral injury occurred after birth or after completion of sulcation. 3. The gyri are narrowed and the sulci widened toward to frontal pole. 4. Paracolic sulci are lateral depressions of the peritoneum investing the cecum. 5. Results: Various fissures, sulci and gyri of the fetal brain appeared sequentially according to the chronological stages and were demonstrated very well on MR imaging. 6. Sulci and gyri of the left and right hemispheressymmetrical basic shape is the leaf and the brain to locate an important symbol. 7. Portions of the tiger stripe fractures, or sulci , are visible throughout the image. 8. The left cerebral hemisphere is smaller with deeper sulci and narrower gyri. 9. Moreover, in lissencephaly (smooth brain), an absence of gyri and sulci and occasionally ventriculomegaly may be noted. 10. Diffuse enhancement followed the convolutions of gyri and surface of brainstem, and extended into cerebral cisterns and sulci. 11. People diagnosed with autism also exhibit abnormal cortical convolutions . Specifically, some of their sulci appear to be deeper and slightly out of place as compared with those of healthy subjects. 12. It will be an intriguing challenge to figure out whether such systematic differences in the shapes of neurons in gyri and sulci also affect their function. 13. 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 . 13. Wish you can benefit fromand make progress everyday! 14. MR images show a mild degree of cerebral atrophy, as slight widening of the hemispheric sulci, prominent in the parietal and perisylvian regions. 15. This is cerebral atrophy in a patient with Alzheimer's disease. The gyri are narrowed and the sulci widened toward to frontal pole. 16. In contrast, if the cerebral injury occurred during embryogenesis no prominent sulci will be present. 17. Our discovery hinted that the physical forces that mold the gyri and sulci also influence neuronal migration. Developmental studies in humans have bolstered this suggestion. 18. The yellow - tan exudate of acute bacterial meningitis seen here obscures the sulci. 19. The surface of the human brain is convoluted by deep fissures, smaller grooves called sulci, and ridges called gyri. 20. In contrast, neurons located in the deep layers of sulci are stretched and look flattened. The shapes of these cells are consistent with having been modified by mechanical forces as the cortex folded. 21. However, in this view, the most prominent feature is Labtayt Sulci, the approximately .6 mile-deep northward-trending chasm.
