神经科学是一个神经科学.
神经学神经学
医疗成像医学成像

背景情况:

基本震 (ET) 是一种常见的神经疾病,与神经网络功能障碍有关.
以前使用静止状态fMRI的研究忽视了ET中大脑网络的动态性质.
研究动态功能连接 (DFC) 和拓对于理解ET至关重要.

研究的目的:

在基本震 (ET) 中检查动态功能连接 (DFC) 的变化.
探索ET中不同DFC状态内的大脑网络功能拓学的变化.
为了将DFC变化与ET患者的震严重程度相关联.

主要方法:

从144名ET患者和131名健康对照 (NC) 获得的休息状态fMRI数据.
移动窗口方法和K-means集群确定了动态的功能状态.
图形理论分析评估了确定状态的拓组织.

主要成果:

确定了两个不同的DFC状态:"大脑主导"状态和"小脑主导"状态.
与NC相比,ET患者表现出较高比例和较长时间的小脑主导状态,与NC相比,状态过渡较少.
ET在大脑区域的中心性和效率降低,在小脑区域的中心性增加,特别是在小脑主导状态. 这些变化与震严重程度相关.

结论:

基本震的特点是长时间的小脑主导状态和功能拓学的破坏.
这些发现为ET背后的神经生物学机制提供了新的见解.
动态功能连接分析为ET病理生理学提供了新的视角.

Functional Brain Systems: Reticular Formation

Functional Brain Systems: Reticular Formation

The reticular formation is a complex network of gray and white matter located within the brainstem extending from the medulla to the midbrain.
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...
