人工電子耳與年齡相關皮質動態：不匹配負波時延與振幅差異之多層次統合分析

// Cochlear Implant and Age-Dependent Cortical Dynamics: A Multilevel Meta-Analysis of Mismatch Negativity Latency and Amplitude Divergences

本綜合分析比較人工耳蝸（CI）使用者與正常聽力（NH）者的錯配負波（MMN）潛伏期與振幅｜結果顯示成人CI用戶MMN潛伏期明顯延長、振幅降低，反映聽覺神經反應較慢且較弱｜兒童CI用戶則與NH兒童無顯著差異，顯示年齡影響植入後神經處理｜研究支持MMN作為評估CI聽覺功能的電生理工具，但仍需探討早期植入的長期效果。

// This meta-analysis examined mismatch negativity (MMN) differences between cochlear implant (CI) users and normal hearing (NH) listeners, focusing on latency and amplitude. Results showed that adult CI users had significantly prolonged MMN latency and reduced amplitude compared to adults with normal hearing, indicating slower and weaker neural auditory responses. Pediatric CI users did not show significant MMN differences from NH peers, suggesting age influences neural processing outcomes after implantation. The study supports MMN as a useful electrophysiological tool for assessing auditory function in CI users but notes the need for more research on long-term effects of early implantation.
