Abstract Memory, as a core function of our cognitive system, is frequently involved in our behaviors. It is generally considered to include two vital memory systems: Long-term memory (LTM) for storing a limitless amount of information and Working memory (WM) for temporally processing information with limited capacity. Here we mainly summarize the evidence for the interaction between WM and LTM in visual memory system. Clearly, previous research suggests that WM and LTM are not completely independent or compatible, and there exists common mechanisms underlying those two memory systems. For example, the participation of LTM can temporally improve WM capacity; while WM is the core for the formation of LTM. Further evidence show that WM and LTM share similar neural mechanism, especially that medial temporal lobe and prefrontal cortex are involved in both WM and LTM processing. Overall, we argue that LTM and WM are not independent memory system, instead they closely interact with each other. Although we conclude this, little is known how such interaction across memory systems works. Thus, future research should be conducted on several aspects (as we listed in the main text) to understand the interaction between LTM and WM.
