Locations of N1m and P2m dipole sources in the axial plane. A: Two dimensional probability density functions for dipole locations found with bootstrap resampling for the ‘mba’ stimulus during the first pre-training session. The blue and red contour lines indicate the 95% confidence limits for N1m and P2m source localizations, respectively. P2m sources are more anteriorly and medially located compared to N1m sources and right hemispheric sources are more anteriorly located than left hemispheric sources. B: Group mean N1m and P2m source locations observed for two speech stimuli and three sessions indicate consistently separated N1m and P2m sources.
