Paradigm 1 and 2: Language paradigm 1 and 2 respectively; TTP: time to peak expressed in seconds and Ampl: Peak Amplitude of BOLD; R: right hemisphere; L: left hemisphere. Please note that differences in the mean amplitude values between table 3 and figures 2 and 3 are due to the fact, that in the table values were extracted from individual peak voxels, while in the figures they were extracted from the group peak voxel.
