概括
与运动相关的脑震荡 (SRC) 后持续症状的运动员表现出脑顶部大脑激活的增加,这表明感官集成的升级. 然而,这种补偿机制是无效的,无法纠正他们的姿势控制和平衡缺陷.
科学领域:
- 神经科学是一个神经科学.
- 运动医学 运动医学
- 康复 康复 康复 康复
背景情况:
- 轻度创伤性脑损伤 (mTBI),包括运动相关的脑震荡 (SRC),经常导致姿势控制受损.
- 个体可能表现出神经元上调,以保持在病态状态期间的认知和行为功能.
研究的目的:
- 调查SRC后持续症状的运动员是否表现出体感皮层和表皮层中大脑激活的增加.
- 确定这种增加的激活是否是对姿势缺陷的补偿机制.
主要方法:
- 评估了66名运动员 (22名有症状的SRC,22名无症状的SRC,22名对照).
- 在各种平衡条件下 (眼睛开/闭,稳定/不稳定的表面) 使用压力板测量姿势控制.
- 使用功能近红外光谱学 (fNIRS) 在前和后中心皮层上监测大脑氧化.
主要成果:
- 有症状的运动员表现出比对照者更大的姿势摆动,特别是在不稳定的表面上.
- 与对照和无症状运动员相比,在所有平衡条件下,在有症状的运动员中观察到 parietal cortex 中大脑激活的增加.
- 这种增强的激活表明,在有症状的运动员中,感官整合过程受到上调.
结论:
- 在持续症状的脑震荡运动员中,表皮和体感皮层激活的增加反映了上调的感官整合.
- 尽管有这种上调,但补偿性神经元机制似乎不足以克服脑震荡后的姿势控制和平衡缺陷.

01:28Major Somatic Sensory Pathways
1.3K
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...

5.1K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...
