概括
帕金森病患患有脱节性关节炎的患者表现出亚thalamic核 (STN) 单单元活性 (SUA) 的改变. 深度大脑刺激 (DBS) 调节了STN SUA和改善了口音,表明STN在语言中的作用.
科学领域:
- 神经科学是一个神经科学.
- 语音科学 语言科学
- 神经学 神经学
背景情况:
- 帕金森病 (PD) 常常会导致脱节症,影响语音清晰度.
- 亚thalamic核 (STN) 涉及运动控制,但其在PD相关的脱节症中的作用不太清楚.
- 调查STN功能和深度大脑刺激 (DBS) 对PD患者单单元活动 (SUA) 的影响至关重要.
研究的目的:
- 为了研究STN功能和DBS对帕金森病患者SUA的影响.
- 为了分析STN神经元活动模式在辅音发音期间.
- 为了在PD患者中比较SUA,有或没有脱关节障碍,并评估DBS的影响.
主要方法:
- 记录了16名PD患者的STN SUA,这些患者表达了中文Pinyin辅音.
- 根据发音方式/位置对辅音进行分类,用于SUA集群分析.
- 将患者分为正常关节和缺关节症组,基于二度动力学 (DDK) 评估.
- 分析了平均发射速度 (FR),高峰时间和响应强度.
- 包括7名PD患者进行手术内DBS测试.
主要成果:
- STN神经元编码着发音,按方式将辅音聚集在一起.
- 确定了两种SUA波形类型 (类型1阴性,类型2阳性尖峰).
- 患有脱发性关节炎的患者表现出1型平均FR增加和2型响应强度降低.
- 术内DBS加速DDK,降低1型平均FR,增加2型平均FR.
结论:
- 在单个单元层面上,STN在和音符编码和失声症中起着至关重要的作用.
- STN SUA的射击模式和DDK性能可以通过DBS进行修改.
- 研究结果强调STN是PD相关语音缺陷的潜在治疗目标.

192
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.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

01:15Parkinson's Disease: Overview
447
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...

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.
