新颖性是创造性思维的一个重要特征,但是新颖的思想“是什么时候在大脑的什么位置产生”仍然是个谜.实验用奇特的照片和几何图形作为触发汉字新语义的手段,采用ERP技术研究创造性思维新颖性的神经机制.结果发现:新语义和原语义的差异波有一个明显的正波峰(P440ms),它与新颖性产生的过程有关,偶极子分析结果表明P440ms的产生源定位在前额叶下回. Novelty is an important feature of creative thinking, but the novel thinking “when is it generated in the brain” is still a mystery.Experimental use of peculiar photos and geometry as a means to trigger the new semantics of Chinese characters, using ERP technology The neural mechanism of novelty of creative thinking is studied.The results show that there is an obvious positive peak (P440ms) in the difference between the new semantics and the original semantics, which is related to the process of novelty, and dipole analysis shows that the source of P440ms Back in the prefrontal folds.
