Group-averaged data showing peak intensity values () and coordinates (mm in Talairach space) for activated clusters (closest Brodmann areas in parentheses) in each of the three conditions compared to the resting state. Corrected activation threshold = , . (1)Activity spread into intraparietal sulcus in 58% of listeners. (2)Activation in SMG, but peak was more localized to angular gyrus in 29%, and intraparietal sulcus in 21% of listeners.
