概括
帕金森病 (PD) 的研究表明,亚thalamic核 (STN) 和皮质中的夸张的β爆发与布拉迪基尼西亚相关. 皮层爆发先于STN爆发,症状恶化与皮层爆发活动增加有关.
科学领域:
- 神经科学是一个神经科学.
- 生物医学工程 生物医学工程
- 运动障碍 运动障碍
背景情况:
- 过度的亚thalamic核 (STN) β活性与帕金森病 (PD) 运动障碍有关.
- 以前的研究还没有完全描述STN和皮层爆发动态或它们与勃拉迪基尼西亚的联系.
研究的目的:
- 在自然主义行为中定义传感运动皮层和STN爆发特征.
- 从运动皮质记录中评估STN爆发的可预测性.
- 通过可穿戴传感器将爆发特征与连续布拉迪基尼西亚测量相关联.
主要方法:
- 分析了1046小时的无线双边传感器皮质和STN记录.
- 包括5名帕金森病患者的数据.
- 使用可穿戴传感器同时测量勃拉迪基尼西亚.
主要成果:
- 与皮层爆发相比,STN爆发的时间较长,爆发间的间隔较短.
- 在结构之间的长爆 (>200 ms) 中观察到时间重叠 (>30%),皮质爆发在STN爆发之前约为8 ms.
- 皮层爆发速度和持续时间的增加与勃拉迪基尼西亚的恶化相关,而STN爆发性质显示出反向关系.
结论:
- 感官运动皮层β爆发之前的STNβ爆发有很短的延迟.

Parkinson's Disease: Overview
419
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...

Parkinson's Disease: Treatment

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.

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.
