高度熟练的多语种人与单语种人相比,显示出明显的白质形态差异. 大脑路径的这些变化表明,神经通信效率提高了处理多种语言的效率.
科学领域:
- 神经科学是一个神经科学.
- 认知神经科学 认知神经科学
- 语言学的语言学.
背景情况:
- 语言处理涉及通过白质通道跨大脑区域的复杂通信.
- 虽然研究了双语对白质的影响,但多语言用户的大脑变化仍然不太了解.
研究的目的:
- 研究高熟练的多语种人与单语种人的白质形态差异.
- 探索使用多种语言如何影响大脑结构和神经通信.
主要方法:
- 基于Fixel的分析被用来量化白质形态学.
- 多语言 (4+语言) 群体与单语言控制群体之间的比较.
主要成果:
- 多语言者在背部和腹部语言路径中表现出更高的纤维截面和更低的纤维密度.
- 纤维横截面,密度和完整性的下降在多语种人体的体,体和皮层-脊柱管中被注意到.
- 这些发现表明,与多语言相关的神经通信模式发生了变化.
结论:
- 多语言与特定的白质形态变化有关.
- 这些大脑变化表明不同的神经通信效率支持多种语言使用.
- 结果与解释多语言个体大脑可塑性的模型一致.

Higher Mental Functions of the Brain: Language
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
