“…The combination of dual‐color GRASP and engram‐tagging technique (Choi et al, 2018; Lee et al, 2023) or neuronal inhibition marker (Dong et al, 2023) during different learning tasks (e.g., space or object vs. time) will visualize the difference of synaptic connectivity relating to different types of memory. The oscillatory activity of cell‐type‐specific pathway can be further elucidated by extracting pathway‐specific activity from local‐field‐potential data using blind‐source separation technique (Fernandez‐Ruiz et al, 2012, 2017, 2021; Herreras et al, 2015; Makarova et al, 2011; Osanai et al, 2023; Schomburg et al, 2014) or by utilizing genetically encoded voltage indicators (Cho et al, 2020; Kannan et al, 2022; Marshall et al, 2016). These technologies promote understanding of detailed cell‐type‐specific connections in MEC‐HPC circuit and their contributions to episodic memory.…”

Episodic memory, which refers to our ability to encode and recall past events, is essential to our daily lives. Previous research has established that both the entorhinal cortex (EC) and hippocampus (HPC) play a crucial role in the formation and retrieval of episodic memories. However, to understand neural circuit mechanisms behind these processes, it has become necessary to monitor and manipulate the neural activity in a cell‐type‐specific manner with high temporal precision during memory formation, consolidation, and retrieval in the EC‐HPC networks. Recent studies using cell‐type‐specific labeling, monitoring, and manipulation have demonstrated that medial EC (MEC) contains multiple excitatory neurons that have differential molecular markers, physiological properties, and anatomical features. In this review, we will comprehensively examine the complementary roles of superficial layers of neurons (II and III) and the roles of deeper layers (V and VI) in episodic memory formation and recall based on these recent findings.
