To provide researchers with a systematic reference on initial contact with working memory and creativity, we elucidated an essential bibliometric analysis of publications based on the Web of Science database. Results were as follows: (a) Related research started in 2003 and entered a period of rapid development since 2013, with more than 20 articles published annually; (b) Roger E. Beaty and Benedek Mathias had the most publications, while Ryuta Kawashima, Hikaru Takeuchi, and Yasuyuki Taki had the most extensive cooperation with others; (c) only 9 out of 527 organizations had formed locally finite cooperative networks; and (d) eight major research popular topics were identified: creativity, cognition, memory, working memory, performance, fMRI, cognitive control, and brain. Enhancing the study of the neural mechanisms of working memory and creativity through fMRI or functional connectivity is of great significance so that we can understand how brain regions interact not only with brain regions that are directly connected structurally but also with those that are not structurally connected.

Many scientific inventions (SI) throughout history were inspired by heuristic prototypes (HPs). For instance, an event or piece of knowledge similar to displaced water from a tub inspired Archimedes’ principle. However, the neural mechanisms underlying this insightful problem solving are not very clear. Thus, the present study explored the neural correlates used to solve SI problems facilitated by HPs. Each HP had two versions: a literal description with an illustration (LDI) and a literal description with no illustration (LDNI). Thirty-two participants were divided randomly into these two groups. Blood oxygenation level-dependent fMRI contrasts between LDI and LDNI groups were measured. Greater activity in the right middle occipital gyrus (RMOG, BA19), right precentral gyrus (RPCG, BA4), and left middle frontal gyrus (LMFG, BA46) were found within the LDI group as compared to the LDNI group. We discuss these results in terms cognitive functions within these regions related to problem solving and memory retrieval. [ABSTRACT FROM AUTHOR]
