已经存在的记忆在重新激活后可以被修改的概念已经得到了越来越多的实验支持,经验数据在物种和记忆范式中积累。然而,没有证据表明系统级无任务的内存修改的内在签名。在这里,使用行为,脑刺激和神经影像学的范例相结合,我们报告说,非侵入性经颅磁刺激干扰与重新激活的运动记忆改变离线无任务的皮质-纹状体区域间的功能连接,减少它相比,刺激中的重新激活的记忆是完整的。此外,调制功能连接预测离线记忆修改。这种功能连接的减少在额外执行记忆任务后恢复,并且干扰不影响控制小脑皮层功能连接。这第一次证明,内在的无任务离线大脑活动可以通过与现有记忆的非侵入性交互来调节,并且与记忆强度变化的行为测量密切相关。
The notion that already existing memories can be modified following their reactivation has received an increasing amount of experimental support, with empirical data accumulating across species and memory paradigms. However, there is no evidence for systems-level task-free intrinsic signatures of memory modification. Here, using a combination of behavioral, brain stimulation and neuroimaging paradigms, we report that non-invasive transcranial magnetic stimulation interference with a reactivated motor memory altered offline task-free cortico-striatal inter-regional functional connectivity, reducing it compared to stimulation in which the reactivated memory was intact. Furthermore, the modulated functional connectivity predicted offline memory modification. This reduction in functional connectivity recovered following additional execution of the memorized task, and the interference did not affect control cerebellar-cortical functional connectivity. This demonstrates for the first time that intrinsic task-free offline brain activity can be modulated by non-invasive interaction with existing memories and strongly correlates with behavioral measurements of changes in memory strength.
