功能磁共振成像视角下的脑功能连通性分析与脑可塑性

Brain Functional Connectivity Analysis and Brain Plasticity Form Perspective of fMRI Technique

依据功能磁共振成像技术探究脑功能可塑性,对解码人脑认知活动与模拟类脑智能具有十分重要的意义,同时也是一项极具挑战性的工作。然而,脑功能可塑性可通过脑功能连通的变异性来体现,而该变异性的捕捉又依赖于有效的脑功能连通性分析模型。因此,本文首先就当前主要的脑功能连通性分析方法进行了综述,并分析了各方法的局限性;然后基于脑功能连通性研究的证据,总结与分析了脑功能可塑性与职业因素之间的复杂关系;最后对脑功能连通性分析模型、脑功能可塑性等研究方向进行了展望。

Based on functional magnetic resonance imaging（fMRI）technique,exploring the brain plasticity has a great role in the decoding of the human brain activity and simulating the brain intelligence,and it is also a challenging task.However,the brain functional plasticity could be reflected by the variability of the functional connectivity,which closely depends on the effective analysis models.Thus,firstly,the key brain functional connectivity analysis methods are reviewed and the corresponding limitations of each method are also analyzed.Then,on the evidence from the researches of brain functional connectivity,the complex relationships between the brain functional plasticity and occupational factors are summarized and analyzed.Finally,the future research directions of the brain functional connectivity analysis models and the brain functional plasticity are recommended and discussed.
