大脑发育遵循传感运动-关联轴,在童年和青春期,传感运动区域的连接性得到加强,关联皮层的下降. 这完善了已建立的皮层层次结构.
科学领域:
- 神经科学是一个神经科学.
- 发育神经科学的发展神经科学.
- 认知神经科学 认知神经科学
背景情况:
- 理论上,人类大脑的成熟遵循一个层次化的感觉运动关联轴.
- 这个轴从单模传感运动皮层到跨模协会皮层.
研究的目的:
- 调查儿童和青少年时期的功能连接发展是否与感觉运动关联皮质层次结构保持一致.
- 为了在多个大规模,独立的神经成像数据集中测试这个假设.
主要方法:
- 利用了四个大,独立的数据集 (总共n=3355,年龄在5-23岁之间).
- 包括费城神经发育队列,纳森·克莱恩研究所-洛克兰样本,人类连接组项目:发展和健康的大脑网络.
- 分析了传感运动-关联轴的功能连接的发展.
主要成果:
- 在所有数据集中,功能连接的发展沿着传感运动-关联轴系统地变化.
- 感官运动区域的连接性增加.
- 协会皮层的连接性下降,加强皮层层次结构.
结论:
- 感觉运动关联轴代表了功能连接发展的主要组织原则.
- 这些发现支持并完善了在人类发育过程中皮质组织的等级模型.
