Amygdala是英語名詞,音標為英[əˈmɪɡdələ]/美[əˈmɪɡdələ],複數形式為amygdalae。其核心釋義包括解剖學中的杏仁核(大腦邊緣系統灰質團塊)與扁桃腺(咽喉部組織),以及植物學中的苦巴旦杏。作為跨學科術語,該詞在神經科學及醫學領域套用最廣,常指涉大腦情感記憶調節中樞。
解剖學中,杏仁核由基底外側核、中央核等亞區構成,與海馬體同為邊緣系統關鍵組件,負責情緒生成及恐懼反應調控。20世紀90年代起,研究證實其通過GABA能突觸參與焦慮調節,並與前額葉皮層協同影響情景記憶處理。21世紀以來,影像學及分子生物學研究揭示了杏仁核在神經退行性疾病、強迫症及攻擊行為中的病理機制,例如TDP-43蛋白異常沉積、帕羅西汀治療引發的體積變化等。實驗室模型中,其功能研究涵蓋恐懼記憶再鞏固、癲癇動物建模及針刺鎮痛機制等領域。
