如何增強長期記憶?清大腦科團隊找到答案
學習一般需要重複多次,才能由暫時的短期記憶固化為永久的長期記憶。神經科學家約30年前就知道,CREB基因轉錄因子在多次間斷式的學習後會活化,進而觸發一系列新蛋白質的合成而形成長期記憶。但為何有些事件我們經歷一次就永久記得? 是不一樣的分子機制嗎? 清華大學腦科學研究中心團隊以果蠅的嗅覺與電擊關聯性學習測試,發現腦神經網路是以一種「雙開關機制」來調控長期記憶的形成。
果蠅有兩個CREB轉錄因子基因,CREBA與CREBB。團隊發現將CREBA轉錄因子表現於左右腦各一顆的DAL神經元,果蠅僅需一次「弱」學習,就可以形成長期記憶。在正常果蠅,長期記憶無法在弱學習後形成是因為DAL神經元內的CREBB蛋白質抑制了CREBA蛋白質活性;當給予十次的「強」訓練後、CREBA基因被活化,並產生新蛋白質解除CREBB蛋白質的抑制作用,且促進下游記憶蛋白的表現,進而形成長期記憶。CREBA/CREBB相互抑制,依學習的強度調控兩者之間的平衡,進而促進或抑制成長期記憶的形成,此發現2021年發表於〈美國國家科學院院刊〉。(more)

Drosophila Memory Connectome
To understand how the brain controls behavior and cognition, our interdisciplinary team is the first among the world to construct the 3D fly brain database at single neuron resolution. This makes the team featured in The New York Times article, titled "Decoding the Human Brain, With Help From a Fly". Base on this map, we also found that learning-induced new protein synthesis occur in only few brain neurons for the formation of long-term memory and pulished in Science magzine. Our team will continously focus on understanding how pairing external odor information with punishment or reward forms long-term memory in fruit flies.
本研究團隊於2010年12月發表了解析度到達單細胞層次之果蠅全腦網絡立體圖譜,獲刊於《現代生物學》雜誌,廣受國內外媒體報導,紐約時報更盛讚此研究為人類全腦圖譜解碼之第一步。藉由此圖譜,本團隊更發現為了現儲存長期記憶所引發的蛋白質新生,僅發生在果蠅腦中少數幾顆特定的神經細胞內,並成為國內首位以長篇論文形式發表在《科學》雜誌之研究。
我們會持續針對果蠅長期記憶形成的分子機制以及嗅覺神經網路做更深入的探索。
