// Oscillatory brain activity reflects semantic and phonological activation during sentence rehearsal
本研究利用磁力腦圖（MEG）探討大腦如何維持口語短期記憶中的語意與語音資訊｜語意干擾激活左側中顳葉及雙側內側顳葉，語音干擾則涉及更廣泛且左側偏重的顳葉、額葉與頂葉區域｜結果顯示語意與語音維持有獨特但重疊的神經基礎，且短暫干擾不影響句子重複能力。
// This study used magnetoencephalography (MEG) to examine how the brain maintains semantic and phonological information in verbal short-term memory. Participants rehearsed short sentences while hearing auditory distractors that were semantically or phonologically related or unrelated. Semantic interference activated the left middle temporal and bilateral medial temporal regions, while phonological interference was more widespread and left-lateralized, involving temporal, frontal, and parietal areas. These findings show distinct but overlapping neural bases for semantic and phonological maintenance, with transient distractor effects that do not impair sentence repetition.
