N1 CAEP development in cochlear implanted children. A. Cortical auditory evoked potentials (CAEPs) recorded in normal hearing children ages 0 to 15 years. Time in milliseconds is shown on the horizontal axis, and amplitude in microvolts on the vertical axis. The grand average waveform per age group, number of subjects included in the grand average, and percentage of children showing the N1 for that age group are described in the panels to the right of the waveforms. Developmental changes in P1 and N1 latencies are depicted by the dashed lines. B. CAEP grand average waveforms in early cochlear implanted children (implanted under 3.5 years). C. CAEP grand average waveforms in the mid cochlear implanted group (implanted between 3.5 and 7 years). D. CAEP grand average waveforms in the late cochlear implanted group (implanted after 7 years). For panels B, C and D, the grand average waveform per age group, the number of subjects included in the grand average, mean implant experience, fit age, and percentage of children showing the N1 for the specific age group are described for each age group.
