基於電生理的電極選擇有助提升人工電子耳使用者的語音感知能力

// Electrophysiologically-based electrode selection has the potential to improve speech perception in cochlear-implant users

本研究利用40Hz電刺激誘發聽覺穩態反應（eASSR）客觀測量電極神經調制｜選取eASSR反應較強或較弱的電極製作個人化地圖｜結果顯示強反應電極地圖提升語音辨識表現，優於弱反應電極，但仍不及臨床標準地圖｜證實eASSR導向的電極選擇能促進人工耳蝸個別化調整及語音理解效果。

// This study aimed to improve cochlear implant (CI) speech perception by using the electrically-evoked auditory steady-state response (eASSR) as an objective measure of neural modulation across electrodes. Researchers recorded 40-Hz eASSRs along the electrode array and created individualized maps selecting electrodes with better or poorer temporal envelope encoding. They found that maps with electrodes showing stronger eASSRs led to better speech perception than those with poorer electrodes, although both were still inferior to the standard clinical map. The findings suggest that objective, eASSR-based electrode selection could enhance individualized CI fitting and speech outcomes.
