研究人员发现,大脑活动模式,特别是感觉运动皮层的mu-rhythm功率和阶段,预测皮质脊髓刺激性对运动皮层腿部表示. 这可能有助于治疗步态和平衡障碍.
科学领域:
- 神经科学是一个神经科学.
- 发动机控制器的控制器
- 大脑与计算机的接口
背景情况:
- 运动皮层 (M1) 手表的皮层脊髓刺激受感官运动肌肉节奏的影响.
- 使用EEG-TMS预测M1腿的表现刺激性还不清楚.
研究的目的:
- 为了研究M1腿代表的传感运动EEG信号和皮质脊髓刺激性之间的预测关系.
- 探索 mu-rhythm 阶段和功率以及其他频段在预测 M1 腿部兴奋性的作用.
主要方法:
- 16名健康受试者接受了导航的焦点横磁刺激 (TMS),以准前肌肉热点.
- 运动唤起的潜能 (MEP) 和电脑电图 (EEG) 同时记录.
- 使用了以感觉运动皮层为中心的Hjorth编辑.
主要成果:
- 高马频段功率与MEP振幅呈正相关,而β频段功率则呈反相关.
- 单独的律阶段并不能预测MEP的幅度.
- 观察到mu功率和mu相之间的显著相互作用,影响了MEP振幅.
结论:
- 来自感觉运动皮层的EEG信号,包括mu-功率/相相互作用和其他频段,预测M1腿部表示的皮质脊髓刺激性.
- 这些发现可能会为步态和平衡障碍的脑状态依赖刺激提供指导.

The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...
