(a) Grand average pseudo‐Z maps of cortical activity indicate that monaural click‐trains evoked contralateral dominant activation in adolescents whereas tone‐bursts evoked right hemispheric dominant activation, regardless of ear stimulated in a similar aged cohort. (b) Click‐train stimulation of the left ear evoked significantly increased activity in the right than left auditory cortex (p = .002), whereas right ear stimulation evoked bilaterally symmetric cortical activation (p = .332). Averaged across three time windows, dipole moments were significantly larger in the right auditory cortex than the left auditory cortex in response to tone‐bursts to either ear (left ear stimulation: p = .014, right ear stimulation: p = .026). (c) No significant effects on latencies were found bar longer latencies in the right cortex ipsilateral to right tone‐burst stimulation during the P2 time window (p = .018) (*p < .05, **p < .01)
