Abstract

This systematic review considered evidence of children’s and adolescents' typical brain connectivity development studied through resting-state functional magnetic resonance imaging (rs-fMRI). With aim of understanding the state of the art, what has been researched thus far and what remains unknown, this paper reviews 58 studies from 2013 to 2023. Considering the results, rs-fMRI stands out as an appropriate technique for studying language and attention within cognitive domains, and personality traits such as impulsivity and empathy. The most used analyses encompass seed-based, independent component analysis (ICA), the amplitude of the low frequency fluctuations (ALFF), and fractional ALFF (fALFF). The findings highlight key themes, including age-related changes in intrinsic connectivity, sex-specific patterns, and the relevance of the Default Mode Network (DMN). Overall, there is a need for longitudinal approaches to trace the typical developmental trajectory of neural networks from childhood through adolescence with fMRI at rest.

关于健康儿童和青少年大脑连通性的 fMRI 研究的全面系统回顾：当前见解和未来方向

这篇系统性综述探讨了通过静息态功能磁共振成像（rs-fMRI）研究儿童和青少年典型大脑连接发展的证据。本文回顾了 2013 年至 2023 年期间的 58 项研究，旨在了解目前的研究现状、迄今为止的研究成果以及尚存在的未知因素。研究结果表明，rs-fMRI 是研究认知领域中语言和注意力以及冲动和移情等人格特质的合适技术。最常用的分析包括基于种子的独立成分分析（ICA）、低频波动振幅（ALFF）和分数 ALFF（fALFF）。研究结果突出了一些关键主题，包括内在连通性中与年龄相关的变化、性别特异性模式以及默认模式网络（DMN）的相关性。总之，有必要采用纵向方法，利用静息状态下的 fMRI 追踪神经网络从儿童期到青春期的典型发展轨迹。

期刊介绍： The journal publishes theoretical and research papers on cognitive brain development, from infancy through childhood and adolescence and into adulthood. It covers neurocognitive development and neurocognitive processing in both typical and atypical development, including social and affective aspects. Appropriate methodologies for the journal include, but are not limited to, functional neuroimaging (fMRI and MEG), electrophysiology (EEG and ERP), NIRS and transcranial magnetic stimulation, as well as other basic neuroscience approaches using cellular and animal models that directly address cognitive brain development, patient studies, case studies, post-mortem studies and pharmacological studies.
