Evoked source activity for N2. (A) Axial views of each group mean omnibus-corrected pseudo-Z (higher signal-to-noise-ratio in red) maps show regions of activation during N2 upon stimulation of the left and right ears. Activity localized to both auditory cortices in all conditions and groups. (B) Peak dipoles in the auditory cortices were located at similar locations in the left (blue) and right (red) auditory cortices upon stimulation of the left (dark colour) and right (light colour) ear. For each group, the mean ± SE (coloured) and individual (gray) maximum peak (C) dipole moments (nAm) and (D) latencies extracted from chosen voxels are shown for the left (blue) and right (red) auditory cortices upon stimulating the ipsilateral (ipsi; triangles) and contralateral (contra; circles) ear in each group. CI = cochlear implant; HA = hearing aid; *P < 0.05.
