生物谷報(bào)道：發(fā)表在7月13日的《科學(xué)》雜志上的一篇研究報(bào)告說,，神經(jīng)科學(xué)家在人類大腦中發(fā)現(xiàn)了一個(gè)主動(dòng)地抑制記憶的機(jī)制并揭示了一個(gè)兩個(gè)步驟的抑制過程,。

    心理學(xué)家對(duì)是否真能抑制記憶的爭(zhēng)論已經(jīng)有 100年了。Brendan E. Depue和論文共同作者用功能磁共振成像(fMRI)來監(jiān)測(cè)大腦中支持記憶處理的區(qū)域,。被測(cè)試者被要求主動(dòng)地記住一個(gè)記憶或主動(dòng)地抑制一個(gè)記憶,，研究人員發(fā)現(xiàn)被測(cè)試著能抑制記憶,。然后他們檢查了控制記憶的大腦區(qū)域前額葉皮層的fMDI圖像，發(fā)現(xiàn)前額葉皮層的一個(gè)部分與記憶的感覺方面有關(guān),，而前額葉皮層的另一個(gè)部分抑制支持記憶過程以及支持與記憶有關(guān)的感情的大腦區(qū)域,。這項(xiàng)研究延伸了對(duì)控制記憶和思想的大腦機(jī)制、尤其是對(duì)比如創(chuàng)傷后應(yīng)激癥和強(qiáng)迫綜合癥患者所遭受的感情記憶和思想失控的機(jī)制的了解,。

Brendan E. Depue, Tim Curran, and Marie T. Banich
Science 13 July 2007: 215-219.
During normal suppression of emotional memories, the prefrontal cortex inhibits memory-related brain regions, a process that may go awry in certain psychiatric conditions.
