Peaks of brain regions active more for math than language (P < 0.05, cluster corrected; P < 0.01 cluster-forming threshold; 10 mm minimum distance between peaks). Coordinates reported in MNI space. Peak t: t values corresponding to local maxima; mm²: area occupied by cluster on cortical surface; P_cluster: P value for entire cluster.
