1. The surface of cerebrum is increased by many gyri.

2. Objective: Localizing pre- and postcentral gyri on sagittal sections by medullary processes.

3. Moreover, in lissencephaly (smooth brain), an absence of gyri and sulci and occasionally ventriculomegaly may be noted.

4. The gyri are narrowed and the sulci widened toward to frontal pole.

4. try its best to collect and build good sentences.

5. Diffuse enhancement followed the convolutions of gyri and surface of brainstem, and extended into cerebral cisterns and sulci.

6. 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.

7. Sulci and gyri of the left and right hemispheressymmetrical basic shape is the leaf and the brain to locate an important symbol.

8. Activation of fusiform gyri by faces was strongly affected by attentional condition, but the left amygdala response to fearful faces was not.

9. This area of firm, whitened gyri that are broader than surrounding normal gyri is typical for tuberous sclerosis.

10. Note that both pre - and post - central gyri, where the primary sensorimotor cortices are located, are relatively hyperperfused.

11. To improve the knowledge of the pathophysiology of many brain areas involved by a lesion, such as the supplementary motor area, insula, premotor cortex, supramarginal and angular gyri.

12. Seen here are remote contusions , mainly of the right inferior frontal lobe. The crests of the gyri are most susceptible to the traumatic forces.

13. MAIN OUTCOME MEASURES:Glucose metabolism of bilateral frontal lobes, bilateral caudate nuclei, bilateral cingulate gyri and bilateral cerebella.

14. 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.

15. It is a reliable and accurate method to localize the gyri and lobes according to the pattern of medullary branches.

16. A coronal section through the frontal lobes reveals extensive contusions involving the inferior gyri.

17. The characteristic feature is the presence of "tubers" which are enlarged and firm, whitened gyri.

18. This is cerebral atrophy in a patient with Alzheimer's disease. The gyri are narrowed and the sulci widened toward to frontal pole.

19. Conclusions: MRI can show the atrophy of HPFs and parahippocampal gyri in patients with memory impairment.

20. 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.

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

22. The surface of the human brain is convoluted by deep fissures, smaller grooves called sulci, and ridges called gyri.

23. The left cerebral hemisphere is smaller with deeper sulci and narrower gyri.
