假如脑损伤发生在生后或脑沟形成后，受累的大脑半球将会出现脑沟加深。
虎纹状裂纹，或者叫做渠沟，在整幅图片里都可以清晰地看见。
颞叶灰质密度减低，脑沟变窄或消失，灰白质界限不清。
图示一例阿尔茨海默氏病患者萎缩的大脑。脑回变窄，脑沟向着前端变宽。
1·Thrush is a degeneration of the frog with a secondary bacterial infection that begins in the central and collateral sulci.
鹅口疮是青蛙的退化，继发于中央和侧沟的继发细菌感染。
2·The involved cerebral hemisphere will have enlarged sulci if the cerebral injury occurred after birth or after completion of sulcation.
假如脑损伤发生在生后或脑沟形成后，受累的大脑半球将会出现脑沟加深。
3·The left cerebral hemisphere is smaller with deeper sulci and narrower gyri.
左侧的大脑半球小于右侧，脑沟较深，脑回也比右侧狭窄。
4·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.
结果：MR成像能很好地显示某些脑裂、脑沟及脑回按时间依次出现的过程；
