摘要
聚合思维是创造性思维的形式之一,但其脑机制 目前还不清楚.采用静息态脑功能成像技术和远距离联想测验,基于低频振荡振幅(ALFF)和局部一致性(ReHo)两种分析方法,研究聚合思维的脑机制.结果发现,远距离联想测验得分与楔前叶的ALFF值显著负相关,与右侧罗兰迪克岛盖区/脑岛的ALFF值显著正相关;同时与左侧额下回的ReHo值显著负相关.研究结合ALFF和ReHo两种指标探讨聚合思维的神经机制,为进一步揭示创造性的本质提供依据.
Abstract
Convergent thinking is a crucial measurable component of creativity,however,the neural basis of conver-gent thinking remains unclear.Using resting-state functional magnetic resonance imaging(rs-fMRI)and remote as-sociation test(RAT),the present study used both ReHo(Regional Homogeneity)and ALFF(Amplitude of Low Frequency Fluctuation)to explore the neural correlates of convergent thinking.Results showed that the score of RAT was significantly negatively associated with ALFF in the precuneus while positively associated with ALFF in the right Rolandic operculum extending into Insula.Meanwhile,the results also revealed that RAT was significantly negatively correlated with the ReHo in the left Inferior Frontal Gyrus(IFG)extending into pars opercularis and the left IFG extending into precentral gyrus.The present research explored for the first time the association between both ALFF and ReHo and convergent thinking measured by RAT.The results were discussed from the possible functions of these brain regions in spatial imagination,information integration and attention orientation.
