新生兒對不同語言語音包絡的神經處理及刺激後功能連結性：一項 fNIRS 研究

// Neural processing of speech envelopes from different languages and post-stimulation functional connectivity in newborns: an fNIRS study

用fNIRS（測量腦血氧）在73名新生兒（中/法/英組）測量語音包絡刺激及刺激前後休息｜所有包絡誘發前顳活化，僅普通話短曝後出現刺激後前額顳功能連結增加，局部自發振幅不變｜顯示短暫語音經驗持續增強腦區協調，可能促進語言網絡保留與成熟，具干預意義

// This study tested how newborns process speech envelopes and whether brief exposure changes post-stimulation brain activity. Using fNIRS, the authors recorded hemodynamic responses and resting-state data in 73 newborns (Mandarin, French, English groups) during envelope stimulation and before/after rest. All envelopes evoked frontotemporal activation, and only brief exposure to Mandarin envelopes produced increased frontotemporal functional connectivity after stimulation without changing local spontaneous amplitude. The findings suggest brief exposure yields persistent enhancement of interregional coordination, which could support early retention and maturation of language networks.
