我们大多数人每天都在使用数字进行计数，估计数量或形式数学，尽管它们很重要，但我们对这些过程的大脑相关性的理解仍在不断发展。十多年前提出的心算的神经功能模型刺激了这一领域的大量研究。通过对功能磁共振成像研究的定量荟萃分析，我们确定了使用数字和计算任务的研究中一致的大脑区域。这些任务在一组共同的区域（如顶下小叶）中引发活动;然而，它们不同的区域是最显着的，例如用于特定算术运算的前额叶皮层的不同区域。鉴于目前的知识，我们提出了一个更新的地形脑图谱的心算与改进的解释能力。(C)2010年爱思唯尔公司All rights reserved.
Most of us use numbers daily for counting, estimating quantities or formal mathematics, yet despite their importance our understanding of the brain correlates of these processes is still evolving. A neurofunctional model of mental arithmetic, proposed more than a decade ago, stimulated a substantial body of research in this area. Using quantitative meta-analyses of fMRI studies we identified brain regions concordant among studies that used number and calculation tasks. These tasks elicited activity in a set of common regions such as the inferior parietal lobule; however, the regions in which they differed were most notable, such as distinct areas of prefrontal cortices for specific arithmetic operations. Given the current knowledge, we propose an updated topographical brain atlas of mental arithmetic with improved interpretative power. (C) 2010 Elsevier Inc. All rights reserved.
