MNI coordinates and local maxima of BOLD increases within the singing network (p < 0.001 uncorrected). For anatomic labeling we used Automated Anatomical Labeling (Tzourio-Mazoyer et al., 2002) or, where already cytoarchitectonically mapped, the Anatomy Toolbox (Eickhoff et al., 2005). n.s., Not significant.
