儿童每天都在使用数字，通常从很小的时候就接受正规的数学训练，因为它是学校课程的主要科目。尽管儿童神经影像学研究的增加，一个全面的神经心理学模型的数学功能的儿童是缺乏的。使用功能性磁共振成像（fMRI）研究的定量荟萃分析，我们确定了符合一组选择标准（例如，全脑分析，协调报告），并报告大脑活动的任务，涉及处理符号和非符号数字与和没有正式的数学运算，我们分别称为数字任务和计算任务。我们提供了14岁及以下儿童的数据，他们完成了这些任务。结果显示顶骨的活动（例如，顶叶下小叶和楔前叶）和额叶（例如，上级和内侧额回）皮质、与心算相关的核心区域以及诸如小脑和屏状核的大脑区域，这些区域通常不作为数学问题解决模型的一部分来讨论。我们提出了一个地形图集的数学过程中的儿童，讨论的发展建构主义的理论模型内的研究结果，并提出了实际的方法考虑，为今后的研究。
Children use numbers every day and typically receive formal mathematical training from an early age, as it is a main subject in school curricula. Despite an increase in children neuroimaging studies, a comprehensive neuropsychological model of mathematical functions in children is lacking. Using quantitative meta-analyses of functional magnetic resonance imaging (fMRI) studies, we identify concordant brain areas across articles that adhere to a set of selection criteria (e.g., whole-brain analysis, coordinate reports) and report brain activity to tasks that involve processing symbolic and non-symbolic numbers with and without formal mathematical operations, which we called respectively number tasks and calculation tasks. We present data on children 14 years and younger, who solved these tasks. Results show activity in parietal (e.g., inferior parietal lobule and precuneus) and frontal (e.g., superior and medial frontal gyri) cortices, core areas related to mental-arithmetic, as well as brain regions such as the insula and claustrum, which are not typically discussed as part of mathematical problem solving models. We propose a topographical atlas of mathematical processes in children, discuss findings within a developmental constructivist theoretical model, and suggest practical methodological considerations for future studies.
