纵观有记载的历史，跨越文化，人类创造了视觉艺术。近年来，创造力的神经基础，包括艺术创造力，已成为一个感兴趣的话题。在这项研究中，我们调查的神经基础的视觉创作过程与专业艺术家和一组控制参与者。我们测试的想法，创造力（规划艺术品）会影响参与默认模式网络（DMN），涉及发散思维和产生新的想法，和执行控制网络（EN），涉及评估和选择的想法之间的功能连接。我们在三种不同的条件下测量了功能性磁共振成像（fMRI）的功能连接：休息，字母表的视觉图像和计划在扫描会话后立即执行的艺术品。与我们的假设相一致，我们发现在创造性任务期间DMN和EN区域之间的连接性更强，并且这种差异在专业艺术家中得到增强。这些发现表明，创造力涉及两个通常被视为对立的大脑网络的专家平衡。
Throughout recorded history, and across cultures, humans have made visual art. In recent years, the neural bases of creativity, including artistic creativity, have become a topic of interest. In this study we investigated the neural bases of the visual creative process with both professional artists and a group of control participants. We tested the idea that creativity (planning an artwork) would influence the functional connectivity between regions involved in the default mode network (DMN), implicated in divergent thinking and generating novel ideas, and the executive control network (EN), implicated in evaluating and selecting ideas. We measured functional connectivity with functional Magnetic Resonance Imaging (fMRI) during three different conditions: rest, visual imagery of the alphabet and planning an artwork to be executed immediately after the scanning session. Consistent with our hypothesis, we found stronger connectivity between areas of the DMN and EN during the creative task, and this difference was enhanced in professional artists. These findings suggest that creativity involves an expert balance of two brain networks typically viewed as being in opposition.
