P1 measures and aural preference at initial CI use. (A) Mean (± 1 SE) peak dipole moments in auditory cortices at initial (≤ 1 month) stage of CI activation reveal a trend toward larger responses to the NH than CI ear in both auditory cortices in the late-onset group (p = 0.06, 6 responses in 6 children) but not in the early-onset group (p = 0.81, 15 responses in 11 children). (B) Corresponding mean (± 1 SE) latencies of peak dipoles show faster responses in the late than early-onset group (p < 0.01). (C) Abnormal (grey area) ipsilateral aural preference was measured in 7 of 10 children at this initial stage which could not be significantly predicted by the onset of SSD (p > 0.05), the age at CI (p > 0.05), or the duration of SSD (p > 0.05). ACipsi-CI: Auditory cortex ipsilateral to the CI ear; ACipsi-NH: Auditory cortex ipsilateral to the NH ear. Note: overlapping data points (− 40.86 and − 40.18%) from two children with congenital onset of SSD (0 years) in C-left plot.
