Grand averaged source waveforms of the three conditions separated by group and hemisphere. The 35% standard probability condition is shown in the upper row, the 50% standard probability condition in the middle row and the 70% standard probability condition in the lower row. The grand averaged source waveforms (solid lines) obtained from the individual dipole moment of MMN for musicians (A) and non-musicians (B) are presented with 95% bootstrapped confidence intervals (gray shaded areas). Time windows in which the 95% confidence interval of the bootstrap around the averaged source waveform did not include zero values were considered to indicate significant deflections. For both groups, the left hemisphere is presented on the left side and the right on the right side. The black triangles indicate the MMN response.
