概括
帕金森病通过影响感官重权来损害姿势控制,导致身体更大的摇摆和大脑活动的改变. 虚拟现实和EEG显示出对监测这些障碍的前景.
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
- 康复科学 康复科学 康复科学
背景情况:
- 帕金森病 (PD) 是一种神经退行性疾病,影响运动控制.
- 姿势不稳定是PD的常见和使人虚弱的症状.
- 感官重权,大脑调整对不同感官的依赖以保持平衡的能力,对于姿势控制至关重要.
研究的目的:
- 为了研究帕金森病患者如何重权感官信息以控制姿势.
- 检查皮质活动模式在PD的感官重权化期间.
- 通过虚拟现实感官组织测试 (VR-SOT) 将PD患者的这些效应与年龄匹配的对照进行比较.
主要方法:
- 在一所大学的研究实验室中进行了一项横截面的试点研究.
- 招募了10名患有异常性PD的参与者和11名健康对照者.
- 在VR-SOT期间收集了压力中心 (COP) 和脑电图 (EEG) 数据,以评估姿势控制和皮质活动 (α频段功率,theta/beta比率).
主要成果:
- 患有PD的参与者表现出明显更大的COP位移,特别是在中侧方向.
- 在依赖视觉输入时,PD患者表现出增加的α功率.

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.

01:15Parkinson's Disease: Overview
456
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...

01:28Major Somatic Sensory Pathways

Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...
