本研究通过比较概念生成过程中大脑激活区域的变化，探讨了时间设计神经认知的特征。共有27名工程研究生使用头脑风暴，形态分析和TRIZ产生的概念，设计问题。使用功能性近红外光谱（fNIRS）测量学生前额叶皮层（PFC）的大脑激活。时间激活技术之间进行了比较。当使用头脑风暴和形态学分析时，随着时间的推移，高度激活的区域始终位于PFC的内侧和右侧。对于这两种技术，时间神经生理模式是相似的。与PFC的内侧和右侧部分相关的认知功能表明与发散性思维和适应性决策有关。相比之下，当使用TRIZ时，随着时间的推移高度激活的区域出现在前额皮质的内侧或左侧，通常与目标导向的计划有关。
The research presented in this paper explores features of temporal design neurocognition by comparing regions of activation in the brain during concept generation. A total of 27 engineering graduate students used brainstorming, morphological analysis, and TRIZ to generate concepts to design problems. Students' brain activation in their prefrontal cortex (PFC) was measured using functional near-infrared spectroscopy (fNIRS). Temporal activations were compared between techniques. When using brainstorming and morphological analysis, highly activated regions are consistently situated in the medial and right part of the PFC over time. For both techniques, the temporal neuro-physiological patterns are similar. Cognitive functions associated to the medial and right part of the PFC suggest an association with divergent thinking and adaptative decision making. In contrast, highly activated regions over time when using TRIZ appear in the medial or the left part of the prefrontal cortex, usually associated with goal directed planning.
