Abstract:

大脑皮层网络有向功能连通性是理解大脑组织行为活动方式的关键。本文探索步枪射击任务中射手大脑网络在脑电信号不同节律下的有向功能连通性,为加速步枪射击训练方法的研究提供神经科学方面的依据。采用扩展概率性因果方法分析步枪射击专家和新手在射击准备(pre-shot)阶段大脑皮层的有效定向功能连接。结果表明,额区、额-中、中央区、顶区和枕区在射击过程中都被激活,并且大脑右半球功能连接数量明显多于左半球。在 pre-shot 阶段,与专家相比较,新手大脑皮层网络参与活动的脑区明显增多、网络节点间的连接强度更大、全局效率值较低。这些结果间接地证明了新手需要更努力地协调更多的资源来完成任务,这与专家功能性脑组织的“神经效率”假说一致
