選擇性聽覺注意在模擬電刺激與聲音刺激中及雙耳間調動不同神經策略

// Selective Auditory Attention Engages Distinct Neural Strategies in Simulated Electric and Acoustic Stimulation Within and Across Ears

本研究利用腦電圖(EEG)比較正常聽力者在模擬電聲結合刺激(EAS)與雙模態刺激(BS)下的語音注意加工機制｜兩種條件皆展現相似的皮層語音追蹤準確度，但EAS呈現較強的腦區間相位同步，BS則表現較高跨頻率整合｜結果揭示EAS與BS運用不同神經策略處理語音，為聽力復健提供具體神經機制依據。

// This study compared neural mechanisms supporting attention-driven speech comprehension in simulated electric-acoustic stimulation (EAS) and bimodal stimulation (BS) conditions using EEG in normal-hearing listeners. Both conditions showed similar accuracy in cortical tracking of attended speech, but EAS involved stronger phase synchronization across brain regions, while BS showed greater cross-frequency integration. These distinct neural coordination patterns were linked to task-related brain responses, indicating different neural strategies for speech processing. Findings clarify how EAS and BS use different neural mechanisms despite similar speech encoding, informing targeted auditory interventions.
