识别任务中的刺激重复导致行为表现的改善（“重复启动”），但在整个任务参与的皮层区域衰减神经反应（“重复抑制”）。虽然很明显，这种普遍存在的大脑-行为关系反映了某种形式的处理效率提高，但它的确切形式仍然难以捉摸。在这篇讨论论文中，我们回顾了四种不同的理论建议，有可能链接重复抑制和启动，特别关注的建议，刺激重复影响提高效率，通过增强神经同步。我们认为，尽管令人兴奋的神经同步在认知过程中的作用，如注意力和知觉，在学习和记忆领域的类似研究，特别是启动，最近的工作一直缺乏。我们强调需要新的研究与足够的时空分辨率，制定一些新的预测，并讨论我们正在进行的努力，解开目前的建议。
Stimulus repetition in identification tasks leads to improved behavioral performance ("repetition priming") but attenuated neural responses ("repetition suppression") throughout task-engaged cortical regions. While it is clear that this pervasive brain-behavior relationship reflects some form of improved processing efficiency, the exact form that it takes remains elusive. In this Discussion Paper, we review four different theoretical proposals that have the potential to link repetition suppression and priming, with a particular focus on a proposal that stimulus repetition affects improved efficiency through enhanced neural synchronization. We argue that despite exciting recent work on the role of neural synchronization in cognitive processes such as attention and perception, similar studies in the domain of learning and memory -and priming, in particular-have been lacking. We emphasize the need for new studies with adequate spatiotemporal resolution, formulate several novel predictions, and discuss our ongoing efforts to disentangle the current proposals.
