  • Coordinates of the clusters maximum and their subpeaks are given relative to our infant brain template. They can be roughly compared to adult Montreal Neurological Institute coordinates after multiplication by a factor of 1.4. The voxel-wise significance level was set at P < 0.01. STS, superior temporal sulcus; IFG, inferior frontal gyrus.
