患有脑的早产婴儿的大脑成像显示,大脑半球之间的空间更大,而不是深灰质大小,与 dystonia 有关. 这一发现有助于理解早产期CP中脑损伤模式. 关键词:脑, dystonia, 过早分娩, 脑成像.
科学领域:
- 神经成像是一种神经成像.
- 儿科神经学 儿科神经学
- 发育神经科学的发展神经科学.
背景情况:
- 大脑麻 (CP) 中的 dystonia 通常与满期婴儿的深灰质损伤有关.
- 在早产婴儿中,与 dystonia 相关的脑损伤模式尚不清楚.
- 这项研究调查了早产婴儿患有CP和 dystonia 的大脑区域大小差异.
研究的目的:
- 为了确定特定的大脑区域尺寸差异是否与早产的CP患者的 dystonia 有关.
- 为了在这个人群中确定 dystonia 的潜在生物标志物.
主要方法:
- 对早产婴儿 (<37周妊娠年龄) 患有CP的回顾性队列研究.
- 在1-5岁之间分析的T1加权脑MRI.
- 测量的大脑结构包括半球间距离,双双脚宽度,侧腔室直径,横脑直径,深灰质区域和体厚度.
主要成果:
- 分析包括了55名受试者.
- 在患有 dystonia (P=0.005) 的受试者中观察到显著更大的半球间距离,这表明皮质体积减少.
- 两组之间没有发现深灰色物质面积或其他测量结构的显著差异.
结论:
- 增加的半球间距离与早产婴儿患CP的 dystonia 有关.
- 深灰色物质的大小不是这个人群中 dystonia 的重要相关因子.
- 研究结果表明皮质变化,而不是深层灰质损伤,可能是CP的早产儿的背后原因.

Cerebellar Structure
Externally, the cerebellum features a highly convoluted surface with numerous folia (narrow ridges) separated by shallow sulci (grooves). The cerebellum is divided into two hemispheres by a thin median structure known as the vermis. The...
Anatomy of the Brain: Major Regions
The cerebrum is the largest section of the brain and divides into left and right hemispheres, separated by a deep fissure. The cerebral outer layer of grey matter — the cerebral cortex — comprises elevations called gyri and shallow groves called sulci. The inner portion of white matter includes long nerve fibers known as axons, which connect...
