本文对工作记忆中注意转移和执行过程的神经成像研究进行了荟萃分析。我们使用基于核的方法分析了来自五种类型移位的31个fMRI和PET研究的峰值激活坐标[NeuroImage 19(2003)513]。对不同类型轮班的分析得出的整体结果比个别类型的分析更一致，这表明不同类型的轮班具有共性。这些区域与工作记忆(WM)中报告的执行过程峰值的基于内核的分析得出的区域有很大、很大的重叠。结果表明，在不同的执行控制操作中，有一组共同的大脑区域活跃，包括内侧前额叶、上、下顶叶、内侧顶叶和运动前皮质。然而，在这些区域中的几个区域内，不同类型的切换产生了空间上可区分的激活焦点。来自注意转移和工作记忆的Meta分析衍生区域的精确位置是以电子方式定义的，并可能在未来的研究中用作感兴趣的区域。(C)2004 Elsevier Inc.保留所有权利。
This paper reports a meta-analysis of neuroimaging studies of attention shifting and executive processes in working memory. We analyzed peak activation coordinates from 31 fMRI and PET studies of five types of shifting using kernel-based methods [NeuroImage 19 (2003) 513]. Analyses collapsing across different types of shifting gave more consistent results overall than analysis within individual types, suggesting a commonality across types of shifting. These areas shared substantial, significant overlap with regions derived from kernel-based analyses of reported peaks for executive processes in working memory (WM). The results suggest that there is a common set of brain regions active in diverse executive control operations, including medial prefrontal, superior and inferior parietal, medial parietal, and premotor cortices. However, within several of these regions, different types of switching produced spatially discriminable activation foci. Precise locations of meta analysis-derived regions from both attention shifting and working memory are defined electronically and may be used as regions of interest in future studies.
