概括
在出生时的妊娠年龄影响大脑发育. 较低的妊娠年龄与大脑组织体积较小和大脑脊髓液体体积较大有关,影响早产婴儿的神经发育.
科学领域:
- 新生儿神经科学
- 发展神经成像
- 产周医学
背景情况:
- 了解早产对早期大脑发育的影响对于神经保护至关重要.
- 目前的知识差距阻碍了针对早产婴儿的个性化神经保护策略.
研究的目的:
- 评估出生时妊娠年龄 (GA) 对终身年龄 (TEA) 的大脑体积的影响.
- 在没有明显的脑损伤的情况下,研究 GA 谱的婴儿的大脑发育.
主要方法:
- 在TEA (月经后40至46周) 左右的婴儿 (25至40周 GA) 中进行了3T脑部MRI.
- 使用MANTiS进行细分,并进行质量控制.
- 线性回归分析了GA与大脑体积之间的关系,控制了月经后的年龄.
主要成果:
- 较高的GA与较低的脑脊液和杏仁体体积相关.
- 没有发现GA与其他测量的大脑体积之间的显著关系.
- 积极的趋势表明大脑组织体积增加,GA增加.
结论:
- 怀孕年龄独立地影响TEA的大脑体积,无论大脑损伤如何.
- 较低的GA与脑组织体积的减少和脑脊液体积的增加相关.
- 过早产生的暴露可能会影响早期的大脑生长,

Anatomy of the Brain: Ventricles
5.1K
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...
