Functional network for melodic singing.

A: Regions of peak neural activity (divided by hemisphere: -x values represent regions in the left hemisphere) during both melodic singing tasks compared with voice perception, prior to training.
B: Regions of peak neural activity (divided by hemisphere) during both melodic singing tasks compared with simple singing, prior to training. All peak/cluster ps≤0.05, corrected. ACC  =  anterior cingulate cortex; aSTG  =  anterior superior temporal gyrus; BA  =  Brodmann area; HG  =  Heschl's gyrus; M1  =  primary motor cortex; mid-PMC  =  mid-premotor cortex; SMA  =  supplementary motor area; STG  =  superior temporal gyrus; vPMC  =  ventral premotor cortex.
