結合皮質節奏地圖現代理解，重新詮釋皮質聽覺誘發反應振幅的頻率依賴性

// Reinterpreting the Frequency Dependence of Cortical Auditory-Evoked Response Amplitudes in Light of Current Understanding of Cortical Tonotopic Organization

本研究探討聽覺皮層頻率地圖（tonotopy）如何影響聽覺誘發反應（AER）｜利用MRI-derived皮層頻率圖與元分析結合模擬，發現穩態AER振幅減弱較明顯，且與Heschl氏迴皮層形態相關｜結果揭示皮層結構對AER產生與振幅變異的關鍵影響，具有重要神經生理意義。

// This study investigates how auditory cortical tonotopy influences auditory-evoked responses (AERs), focusing on frequency-related amplitude reduction. It uses a meta-analysis of AER amplitudes combined with forward simulations based on detailed MRI-derived cortical tonotopic maps. Results show greater amplitude reduction in steady-state than transient-evoked AERs, linked to cortical morphology in Heschl's gyrus. The research offers new insights into how cortical structure affects AER generation and amplitude variability.
