Although both originality and value are considered necessary criteria to identify creative ideas, little is known about how original and valuable ideas are generated in the human brain. To reveal how people monitor and control ongoing processing in the pursuit of original and valuable ideas, high-density electroencephalography (EEG) was used to record electrophysiological signals when participants were performing chunk decomposition tasks via novel-appropriate, novel-inappropriate, ordinary-appropriate and ordinary-inappropriate pathways. The results showed that approximately 100 ms after the problem was presented, novel pathways showed increased theta synchronization in the frontal sites compared to ordinary pathways. Novel pathways were associated with increased alpha desynchronization over the entire brain scale. These theta and alpha oscillations likely indicated rapid monitoring and effective control of novel processing in thinking. In the latter stages of problem solving, particularly during the 2000-2600-ms intervals, increased theta synchronization with decreased alpha desynchronization was found between novel-inappropriate and novel-appropriate pathways, which likely indicated slow monitoring and less control of inappropriate processing in novel thinking. The findings demonstrated the dynamic monitoring and control mechanism in the pursuit of original and valuable ideas.
虽然原创性和价值被认为是识别创意的必要标准，但人们对于人类大脑如何产生原创性和有价值的想法知之甚少。为了揭示人们如何在追求原创性和有价值的想法时监控和控制正在进行的处理，使用高密度脑电图（EEG）记录了参与者通过新颖适当、新颖不适当、普通适当和普通不适当途径进行分块分解任务时的电生理信号。结果表明，在问题呈现后约 100 毫秒，与普通途径相比，新颖途径在前额部位显示出增加的θ同步。新颖途径与整个大脑范围内的α去同步化增加有关。这些θ和α振荡可能表明在思考中对新颖处理进行快速监控和有效控制。在解决问题的后期，特别是在 2000-2600 毫秒的间隔内，在新颖不适当和新颖适当途径之间发现了增加的θ同步和减少的α去同步化，这可能表明在新颖思维中对不适当处理的监控较慢且控制较少。研究结果表明了在追求原创性和有价值的想法时的动态监控和控制机制。
