Brain areas showing significant negative correlation (P < 0.001, cluster corrected at FWE P < 0.05) between the starting age of musical training and the node degrees (musicians). Clusters were obtained via the 18‐connectivity scheme used in SPM. Anatomical labels correspond to the Automated Anatomical Labeling (AAL) [Tzourio‐Mazoyer et al., 2002]. The table reports within‐cluster region size (k; i.e., number of voxels), lowest P‐value per region within the cluster, and its respective MNI coordinates. Small regions within the cluster (k < 4 voxels) were discarded from the resulting table. Abbreviations: L = left, R = right.
