Neural Regulation

39.1K
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

482
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...

科学领域:

  • 神经科学是一个神经科学.
  • 运动障碍 运动障碍
  • 脑部成像 脑部成像

背景情况:

  • 对于患有帕金森病 (PD) 的人来说,步态障碍是一个主要的挑战,严重影响了他们的行动能力和生活质量.
  • 了解这些步行问题背后的皮质机制对于开发有效的干预措施至关重要.

研究的目的:

  • 在PD患者和健康对照者之间,比较前额叶皮层 (PFC),前运动皮层 (PMC) 和主要体感皮层 (PSC) 在PD患者和健康对照者之间走路时的功能连接性.
  • 为了研究大脑活动,功能连接和PD中的步行表现之间的关系.

主要方法:

  • 利用移动功能近红外光谱 (fNIRS) 来测量30名PD患者和22名健康对照患者在行走时氧血球度的变化.
  • 通过计算PFC,PMC和PSC区域的fNIRS通道之间的相互作用强度来评估功能连接.
  • 测量的步行参数,包括步行速度和步伐长度.

主要成果:

  • 与对照组相比,PD患者的步行速度和步伐长度显著减少.
  • 虽然区域内连接没有显著差异,但PD组在PFC,PMC和PSC地区之间显示出更强的区域间功能连接.
  • 在右前运动皮质 (RPMC) 中的步行表现和功能连接之间以及在RPMC和右主体感皮质 (RPSC) 之间观察到积极的相关性.

结论:

  • 在非状态下患有PD的个体存在行走障碍和感觉运动和运动相关大脑区域的功能连接性增加.
  • 针对并可能加强RPMC内部以及RPMC和RPSC之间的功能连接可能是PD相关的步行障碍的有希望的治疗策略.
