概括

帕金森病 (PD) 与大脑网络中广泛的结构功能 (SC-FC) 分离有关. 这项研究显示,与健康对照人群相比,PD患者的大脑网络内和大脑网络之间的SC-FC合发生了变化.

科学领域:

神经科学是一个神经科学.
脑部成像脑部成像
网络科学网络科学

背景情况:

帕金森病 (PD) 涉及神经退行症,超出阴三路径.
网络层面的结构功能 (SC-FC) 合变化对PD的研究不足.
在PD中SC-FC合中亚皮层区域的作用需要进一步研究.

研究的目的:

调查帕金森病 (PD) 中结构功能 (SC-FC) 合的变化.
探索功能性大脑网络内部和之间SC-FC合变异.
了解底层PD的网络层面机制.

主要方法:

扩散张力成像 (DTI) 用于结构连接.
休息状态功能磁共振成像 (rs-fMRI) 用于功能连接.
在53名PD患者和72名健康对照 (HC) 中,系统地构建和分析SC-FC合网络.

主要成果:

与HC相比,在PD患者中观察到的SC-FC合的全球减少.
区域性SC-FC脱在下垂体叶区,角皮质,运动皮质和关联皮质中被发现.
视觉,边缘和协会网络中的内部网络脱;互联网脱涉及视觉,体运动,注意力和默认模式网络. 在PD中发现了皮下皮层-体运动合的增加.

结论:

在脑网络拓学中,PD的特征是广泛的SC-FC脱.
研究结果提供了有关帕金森病相关的大脑网络机制的见解.
改变的SC-FC合突出显示了PD中的网络级失调.

关键词:

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Parkinson's Disease: Overview

Parkinson's Disease: Overview

Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...
