这项功能磁共振成像研究探讨了大脑激活过程中创造性的想法产生使用一种新的方法，允许自发的自我节奏的产生和表达的想法。具体来说，我们解决了一个基本问题，即与仅仅从记忆中回忆旧想法相比，什么样的大脑过程与产生真正新的创造性想法有关。一般来说，创造性想法的产生（即，发散思维）与左前额叶皮层和右内侧颞叶的延长激活以及右颞顶交界处的失活有关。新想法的产生，而不是旧想法的检索，与左下顶叶皮层的更强激活有关，已知该皮层参与心理模拟，想象和未来思维。此外，发现额下回眶部的大脑激活作为创造力的函数而增加（即，原创性和适当性）的想法，指出执行过程的作用，克服占主导地位的，但没有创造性的反应。我们的结论是，想法产生的过程可以被普遍理解为一个国家的集中内部导向的注意力，涉及控制语义检索。此外，左下顶叶皮层和左前额叶可能有助于灵活整合先前的知识，以构建新的和创造性的想法。在自发的自我起搏的想法产生过程中进行功能成像。公开的反应进行了记录和评价的新奇和创造性。研究人员比较了新创造和回忆的想法的大脑激活情况。新想法的产生涉及到左IPC的更强激活。思想的创造性与激活左IFG有关。
This fMRI study investigated brain activation during creative idea generation using a novel approach allowing spontaneous self-paced generation and expression of ideas. Specifically, we addressed the fundamental question of what brain processes are relevant for the generation of genuinely new creative ideas, in contrast to the mere recollection of old ideas from memory. In general, creative idea generation (i.e., divergent thinking) was associated with extended activations in the left prefrontal cortex and the right medial temporal lobe, and with deactivation of the right temporoparietal junction. The generation of new ideas, as opposed to the retrieval of old ideas, was associated with stronger activation in the left inferior parietal cortex which is known to be involved in mental simulation, imagining, and future thought. Moreover, brain activation in the orbital part of the inferior frontal gyrus was found to increase as a function of the creativity (i.e., originality and appropriateness) of ideas pointing to the role of executive processes for overcoming dominant but uncreative responses. We conclude that the process of idea generation can be generally understood as a state of focused internally-directed attention involving controlled semantic retrieval. Moreover, left inferior parietal cortex and left prefrontal regions may subserve the flexible integration of previous knowledge for the construction of new and creative ideas. Functional imaging was performed during spontaneous self-paced idea generation. Overt responses were recorded and evaluated for novelty and creativity. Brain activation of newly created and recalled ideas was compared. The generation of new ideas involved stronger activation of the left IPC. Creativity of ideas was related to activation of the left IFG.
