大脑中突触储存的记忆的重新激活可以使记忆暂时不稳定。在记忆重新稳定(重新巩固)所需的时间里,记忆可以通过失忆症药物减少,也可以通过记忆增强剂增强。记忆表达的变化与大脑中与长期记忆相关的变化有关。许多人认为,这种检索诱发的可塑性是使记忆与新信息更新的理想场所。这一假设已经通过实验进行了验证,从翻译的角度来看,通过尝试更新适应不良的记忆来减少它们的问题影响。在这里,我们回顾了再巩固更新研究的进展,重点介绍了它们的转化利用和解决了再巩固领域最近面临的挑战。
The reactivation of a synaptically stored memory in the brain can make the memory transiently labile. During the time it takes for the memory to re-stabilize (reconsolidate), the memory can either be reduced by an amnesic agent or enhanced by memory enhancers. The change in memory expression is related to changes in the brain correlates of long-term memory. Many have suggested that such retrieval-induced plasticity is ideally placed to enable memories to be updated with new information. This hypothesis has been tested experimentally, with a translational perspective, by attempts to update maladaptive memories in order to reduce their problematic impact. Here, we review the progress on reconsolidation-update studies, highlighting their translational exploitation and addressing recent challenges to the reconsolidation field.
