“…Other than the fNIRS data, the current EEG data thus provided evidence that prosodic variations evoke greater 5 auditory evoked responses, in line with previous data obtained from adult NH listeners (Steinmetzger et al, 2022a). Previous ERP data obtained from pre- (Ni et al, 2021;Vavatzanidis et al, 2015;Vavatzanidis et al, 2018) and post-lingually deafened CI users (Sandmann et al, 2015) reported increased auditory evoked responses with more CI experience. However, these longitudinal studies used non-speech stimuli or isolated syllables rather than continuous speech, limiting comparability with the present findings.…”

In case of severe hearing loss early in life or congenital deafness, cochlear implants (CIs) represent the method of choice to restore hearing and enable language acquisition. While speech intelligibility has been shown to improve during the first year after implantation to then reach a plateau, the underlying neuroplastic changes are poorly understood. Here, we longitudinally compared the cortical processing of speech stimuli in a case-control design with two groups of pre-lingually deafened CI users (4.4 vs. 25.8 months of CI experience) and an age-matched control group with normal hearing (NH; mean group ages ∼9 years). In two experiments, participants were presented with running speech and vowel sequences while fNIRS and EEG data were obtained simultaneously. Despite trends in this direction, cortical activity did not increase significantly with more CI experience and did not approach the higher levels observed in the NH controls. However, in the speech experiment, the less experienced CI group showed an abnormal shift of activity to the right hemisphere not observed in the other two groups. These results hence imply that adaptation to CI-based hearing is not characterised by a gradual increase of activity in left-hemispheric language network, but a reduction of abnormal activity elsewhere.

“…Sharma et al, 1997). A discernible P1 has been observed after about 6 months of CI use in young children (Ni et al, 2021), but compared to normal-hearing (NH) controls, the P1 in paediatric CI users is smaller and delayed (Gilley et al, 2008; Ponton et al, 1996; A. Sharma et al, 2002).…”

“…Studies of sensory loss can provide a model for understanding the mechanism of neural function development. With respect to pre-lingually deaf children, the maturation of the auditory cortex ( Knudsen, 2004 ; Ni et al, 2021 ) and their speech development ( Venail et al, 2010 ) have been influenced due to hearing deprivation. Although cochlear implantation (CI) has become widely used to restore severe-to-profound deafness for pre-lingually deaf children ( Sharma et al, 2015 ), the cochlear device cannot accurately deliver all kinds of sound information, especially prosodic features, possibly because of its limited number of electrodes ( Svirsky, 2017 ).…”

Children’s Neural Sensitivity to Prosodic Features of Natural Speech and Its Significance to Speech Development in Cochlear Implanted Children

Catchy utterances, such as proverbs, verses, and nursery rhymes (i.e., “No pain, no gain” in English), contain strong-prosodic (SP) features and are child-friendly in repeating and memorizing; yet the way those prosodic features encoded by neural activity and their influence on speech development in children are still largely unknown. Using functional near-infrared spectroscopy (fNIRS), this study investigated the cortical responses to the perception of natural speech sentences with strong/weak-prosodic (SP/WP) features and evaluated the speech communication ability in 21 pre-lingually deaf children with cochlear implantation (CI) and 25 normal hearing (NH) children. A comprehensive evaluation of speech communication ability was conducted on all the participants to explore the potential correlations between neural activities and children’s speech development. The SP information evoked right-lateralized cortical responses across a broad brain network in NH children and facilitated the early integration of linguistic information, highlighting children’s neural sensitivity to natural SP sentences. In contrast, children with CI showed significantly weaker cortical activation and characteristic deficits in speech perception with SP features, suggesting hearing loss at the early age of life, causing significantly impaired sensitivity to prosodic features of sentences. Importantly, the level of neural sensitivity to SP sentences was significantly related to the speech behaviors of all children participants. These findings demonstrate the significance of speech prosodic features in children’s speech development.

“…These activity-dependent processes may include improvement in synaptic efficacy and increased myelination ( Gordon et al, 2003 ). The auditory system may rapidly develop within a critical period of 3–6 months after cochlear implantation and enter a maturation period after 12 months ( Ni et al, 2021 ). Most CI children in our study received implantation before 3.5 years old and still had high plasticity of the auditory cortex ( Manrique et al, 1999 ).…”

Background: While a cochlear implant (CI) can restore access to audibility in deaf children, implanted children may still have difficulty in concentrating. Previous studies have revealed a close relationship between sensory gating and attention. However, whether CI children have deficient auditory sensory gating remains unclear.Methods: To address this issue, we measured the event-related potentials (ERPs), including P50, N100, and P200, evoked by paired tone bursts (S1 and S2) in CI children and normal-hearing (NH) controls. Suppressed amplitudes for S2 compared with S1 in these three ERPs reflected sensory gating during early and later phases, respectively. A Swanson, Nolan, and Pelham IV (SNAP-IV) scale was performed to assess the attentional performance.Results: Significant amplitude differences between S1 and S2 in N100 and P200 were observed in both NH and CI children, indicating the presence of sensory gating in the two groups. However, the P50 suppression was only found in NH children and not in CI children. Furthermore, the duration of deafness was significantly positively correlated with the score of inattention in CI children.Conclusion: Auditory sensory gating can develop but is deficient during the early phase in CI children. Long-term auditory deprivation has a negative effect on sensory gating and attentional performance.
