研究人员使用休息状态功能性MRI (rs-fMRI) 数据创建了第一个婴儿特定的大脑图. 这些详细的地图捕捉了婴儿和幼儿早期的大脑发育和功能组织.
科学领域:
- 神经成像是一种神经成像.
- 发育神经科学的发展神经科学.
- 儿童大脑映射 儿童大脑映射
背景情况:
- 休息状态功能性MRI (rs-fMRI) 对于研究婴儿大脑发育至关重要.
- 现有的功能分片地图是以成年人为基础的,不适合婴儿,因为大脑组织不同.
- 开发婴儿专用地图是必不可少的,但由于数据采集和处理困难,这是一项具有挑战性的工作.
研究的目的:
- 开发第一套针对婴儿的,细粒度的,基于表面的皮质功能分片地图.
- 为了解决在儿科神经成像中使用成人衍生地图的局限性.
- 为了解早期大脑功能发育提供资源.
主要方法:
- 利用了从婴儿连接组项目中197名婴儿 (出生至24个月) 的1064个纵向rs-fMRI扫描.
- 采用基于几何折叠特征和功能连接 (FC) 梯度的皮层联合注册.
- 使用对齐的FC梯度数据生成了800多个地块的年龄相关和年龄独立的地块地图.
主要成果:
- 开发了针对婴儿的新型皮质功能分片地图.
- 在婴儿早期 (第一个9个月) 揭示了复杂的功能发展模式.
- 在早期开发过程中确定了局部梯度,网络大小和局部效率的变化.
结论:
- 创建的细粒度婴儿皮质功能分片地图是儿科神经成像的宝贵资源.
- 这些地图可以更准确地研究婴儿动态大脑功能发育的情况.
- 这些地图的公共可用性 (https://www.nitrc.org/projects/infantsurfatlas/) 将推动该领域的发展.

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 various areas...
