Predicting Stroop effect from spontaneous neuronal activity: a study of regional homogeneity

The Stroop effect is one of the most robust and well-studied phenomena in cognitive psychology and cognitive neuroscience. However, little is known about the relationship between intrinsic brain activity and the individual differences of this effect. In the present study, we explored this issue by examining whether resting-state functional magnetic resonance imaging (rs-fMRI) signals could predict individual differences in the Stroop effect of healthy individuals. A partial correlation analysis was calculated to examine the relationship between regional homogeneity (ReHo) and Stroop effect size, while controlling for age, sex, and framewise displacement (FD). The results showed positive correlations in the left inferior frontal gyrus (LIFG), the left insula, the ventral anterior cingulate cortex (vACC), and the medial frontal gyrus (MFG), and negative correlation in the left precentral gyrus (LPG). These results indicate the possible influences of the LIFG, the left insula, and the LPG ...

斯特鲁普效应（Stroop effect）是认知心理学与认知神经科学领域最具稳健性且被广泛研究的经典现象之一。然而，目前学界对脑内在活动与该效应个体差异之间的关联仍知之甚少。本研究通过检验静息态功能磁共振成像（rs-fMRI）信号能否预测健康个体的斯特鲁普效应个体差异，对这一科学问题展开了探索。研究采用偏相关分析，在控制年龄、性别与帧位移（FD）的前提下，检验了区域同质性（ReHo）与斯特鲁普效应量之间的关联。结果显示，左侧额下回（LIFG）、左侧脑岛、腹侧前扣带回皮层（vACC）以及内侧额回（MFG）呈现正相关，而左侧中央前回（LPG）则呈现负相关。上述结果表明，左侧额下回、左侧脑岛与左侧中央前回可能对……
