// The impact of hearing loss on tone discrimination: An fMRI study
本研究利用功能性磁振造影(fMRI)探討早發性聽力損失對中文聲調辨識及腦部活化的影響｜重度與中重度聽損者聲調辨識準確率較正常聽力者低，且重度聽損者表現最差｜fMRI發現所有組別均啟動聽覺相關腦區，重度聽損組左上顳回及Heschl迴活化增強，與聽力閾值相關但與行為表現無明顯關聯｜結果顯示重度聽損者透過腦部聽覺皮質的神經可塑性強化聲調處理，強調多感官訓練在康復中的重要性。
// This study used fMRI to investigate how early-onset hearing loss affects Mandarin tone discrimination and brain activation. Participants with profound and moderate-to-severe hearing loss showed lower accuracy in tone discrimination compared to normal-hearing controls, with profound loss linked to the poorest performance. fMRI revealed all groups activated key auditory brain regions, but those with profound loss had heightened activation in the left superior temporal gyrus and Heschl's gyrus, correlating with hearing thresholds but not behavioral accuracy. The findings suggest stronger auditory cortex recruitment occurs to support tone processing in profound hearing loss, highlighting neural plasticity and the value of multisensory training in rehabilitation.
