While previous studies suggest that the default mode network (DMN) may be altered in dyscalculia, the study of resting\u2010state networks in the development of numerical skills, especially in children with developmental dyscalculia (DD), is scarce and relatively recent. Based on this, this study examines differences in resting\u2010state functional connectivity (rs\u2010FC) data of children with DD using functional connectivity multivariate pattern analysis (fc\u2010MVPA), a data\u2010driven methodology that summarizes properties of the entire connectome.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We performed fc\u2010MVPA on resting\u2010state images of a sample composed of a group of children with DD (<jats:italic>n<\/jats:italic>\u00a0=\u00a019, 8.06\u00a0\u00b1\u00a00.87\u00a0years) and an age\u2010 and sex\u2010matched control group of typically developing children (<jats:italic>n<\/jats:italic>\u00a0=\u00a023, 7.76\u00a0\u00b1\u00a00.46\u00a0years).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Analysis of fc\u2010MVPA showed significant differences between group connectivity profiles in two clusters allocated in both the right and left medial temporal gyrus.
