The Neural Mechanism Of Novelty Generated From Creative Thinking

Creativity whose characters are novel, ambiguous, implicit, overt, conflict and divergent, it is the development of human higher cognitive symbol. Human cognitive experience that goes beyond the existing knowledge to generate new knowledge, this formation process can be rigorous experimental study it. Based on previous large studies have shown that brain mechanisms for creative research involves many aspects, the use of different experimental methods, techniques, materials, and constantly explore creative expression in the brain processing, brain mechanism which is linked with creativity. First of all, creativity is a complex process, explore the creative brain, the premise need to make creativity "pure", which really is the creative process and production process occurs, if mixed with other cognitive processes, then the results are often inconsistent even differ; Secondly, the creative brain mechanism, more researchers are concerned that the creative novelty, because the novelty is an important feature of creative thinking, it is contained in the insight, the set shift, remote association and so on. However, the absence of the novelty of the whole thinking process of separating it "when produced in the brain what position" remains a mystery.In experiment 1 we used a simple combination of materials and graphics as an imaginary object, caused by two kinds of cognitive processing language guide: creative imagination and reproductive imagination, use of high time resolution of Technology (ERP) recording and analysis of both the brain when dynamic change process, in order to further reveal the creative novelty produced in the brain mechanism to provide direct evidence of brain mechanism. It was found that significant difference wave amplitude of P520-550ms existed between creative imagination and reproductive imagination. The result of dipole analysis was the difference wave mostly activated the frontal brain.In experiment 2 we used Chinese characters and the play "catalyst" of the scenes photos of Chinese characters as the experimental materials produced the new semantics of the brain mechanism. Recorded and analyzed the process of semantics produce high time resolution of ERPs and dipole analysis conducted, it can more accurately study the time course of activation of different processes and brain mapping, can reveal the creative thinking process of the brain mechanism of production of novelty provide a more valuable basis. It found a new meaning with the main difference between the novel and original semantics of an obvious wave crest P445ms, and mainly frontal lobe activation.This study shows that the moment of novelty produced in creative thinking after the stimulus onset around 400-500ms, and the frontal lobe of the brain closely associated with the production of novelty.
