【摘要】:人類對(duì)記憶的研究已經(jīng)有一個(gè)多世紀(jì)之久.海馬是記憶形成的重要腦結(jié)構(gòu),新形成的記憶在海馬中編碼后,經(jīng)過(guò)鞏固而得以保持.經(jīng)典記憶模型認(rèn)為記憶在鞏固后愈發(fā)穩(wěn)定,但近期研究發(fā)現(xiàn),鞏固不是一次性過(guò)程,伴隨著記憶提取或再次激活,鞏固好的記憶也會(huì)重新回到不穩(wěn)定狀態(tài),需要再次被鞏固,即再鞏固.再鞏固過(guò)程的發(fā)現(xiàn)揭示了記憶的可塑性,為破壞或更新舊記憶提供了研究窗口.本文從時(shí)間維度,針對(duì)記憶發(fā)生的全過(guò)程,即記憶的編碼,鞏固、再鞏固,直至記憶的遺忘,介紹記憶加工過(guò)程對(duì)應(yīng)的神經(jīng)機(jī)制,討論當(dāng)前的研究進(jìn)展并展望未來(lái)的研究方向.
[Abstract]:Human memory has been studied for more than a century. The hippocampus is an important brain structure for memory formation. The newly formed memory is encoded in the hippocampus and preserved after consolidation. The classical memory model believes that memory becomes more stable after consolidation. But recent research has found that consolidation is not a one-off process. With memory extraction or reactivation, consolidated memories return to unstable states and need to be consolidated again. The discovery of the process of re-consolidation reveals the plasticity of memory and provides a window for the study of destroying or updating old memory. This paper aims at the whole process of memory occurrence, namely, the coding, consolidation, and consolidation of memory, from the time dimension. Until the memory is forgotten, the neural mechanism of memory processing is introduced, the current research progress is discussed and the future research direction is prospected.
