生物谷报道：发表在7月13日的《科学》杂志上的一篇研究报告说，神经科学家在人类大脑中发现了一个主动地抑制记忆的机制并揭示了一个两个步骤的抑制过程。
心理学家对是否真能抑制记忆的争论已经有 100年了。Brendan E. Depue和论文共同作者用功能磁共振成像(fMRI)来监测大脑中支持记忆处理的区域。被测试者被要求主动地记住一个记忆或主动地抑制一个记忆，研究人员发现被测试着能抑制记忆。然后他们检查了控制记忆的大脑区域前额叶皮层的fMDI图像，发现前额叶皮层的一个部分与记忆的感觉方面有关，而前额叶皮层的另一个部分抑制支持记忆过程以及支持与记忆有关的感情的大脑区域。这项研究延伸了对控制记忆和思想的大脑机制、尤其是对比如创伤后应激症和强迫综合症患者所遭受的感情记忆和思想失控的机制的了解。

Prefrontal Regions Orchestrate Suppression of Emotional Memories via a Two-Phase Process

During normal suppression of emotional memories, the prefrontal cortex inhibits memory-related brain regions, a process that may go awry in certain psychiatric conditions.
