- 人类大脑解剖学 人类大脑解剖学
背景情况:
- 转录学已经将基因表达与人类大脑的功能和结构联系起来,主要是在大脑皮层.
- 在关于大脑组织的转录学研究中,大脑下皮层,特别是小脑在很大程度上被忽视了.
研究的目的:
- 研究人类小脑中转录学,功能和结构之间的关系.
- 为了确定小脑中的基因表达模式是否与其解剖学和功能组织相关.
主要方法:
- 利用了死后人类大脑的基因表达数据.
- 集成的转录基因数据与多模式大脑地图.
- 分析了与小脑宏观解剖学和功能分片相关的转录基因梯度.
主要成果:

2.3K
The cerebellum, also known as the "little brain," is located in the posterior cranial fossa, inferior to the tentorium cerebelli and dorsal to the brainstem. It plays a significant role in motor control, coordination, and proprioception.
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...
