Conclusion: There were no apparent differences in speech performance after cochlear implantation between patients with biallelic GJB2 and/or GJB6 mutations and those with deafness of unknown aetiology. These data have important implications for the selection of prognostic indicators of the outcome of cochlear implantation.
Objective: To compare performance after cochlear implantation in children with mutations in GJB2 (connexin 26) and/or GJB6 (connexin 30) and children with deafness of unknown aetiology.
Subjects And Methods: Genetic analysis and speech performance evaluation was determined in 24 patients with (n=11) and without (n=13) biallelic GJB2 and/or GJB6 mutations who underwent cochlear implantation. Speech perception skills were measured 12 and 24 months after surgery. Each patient was classified in accordance with the speech perception category (SPC).
Results: Overall, the two groups showed similar significant improvement in speech perception after implantation.

Background/objectives: In a tonal language like Chinese, phonologically contrasting tones signify word meanings at the syllable level. Although the development of lexical tone perception ability has been examined in many behavioral studies, its developmental trajectory from childhood to adulthood at the neural level remains unclear. This cross-sectional study aimed to examine the issue by measuring the mismatch negativity (MMN) response to a Chinese lexical tonal contrast in three groups.

Purpose: Cognitive dysfunctions are still very common in the chronic phase of stroke when patients are discharged from neurorehabilitation centers. Even individuals who appear to have made a full clinical recovery may exhibit new deficiencies at home. Here, we present evidence of a novel kind of therapy at home aimed at contrasting the heterogenic evolution of stroke patients using a multidomain cognitive approach.

This study used functional near-infrared spectroscopy (fNIRS) to measure aspects of the speech discrimination ability of sleeping infants. We examined the morphology of the fNIRS response to three different speech contrasts, namely "Tea/Ba," "Bee/Ba," and "Ga/Ba." Sixteen infants aged between 3 and 13 months old were included in this study and their fNIRS data were recorded during natural sleep.

Objectives: This umbrella review aims to summarize the major benefits of hearing aid usage in adults by synthesizing findings from published review articles.
Design: A comprehensive search of databases, including MEDLINE, EMBASE, PsycINFO, and Google Scholar, was conducted. The search was limited to English-language review articles published between 1990 and 2023, focusing on hearing aid outcomes in at least 5 adults (aged ≥18 years).

Objectives: The acoustic change complex (ACC) is a cortical auditory evoked potential that shows promise as an objective test of the neural capacity for speech and sound discrimination, particularly for difficult-to-test populations, for example, cognitively impaired adults. There is uncertainty, however, surrounding the performance of the ACC with behavioral measures. The objective of this study was to systematically review the literature, focusing on adult studies, to investigate the relationship between ACC responses and behavioral psychophysical measures.
