Episodic memories are crucial elements that determine our sense of identity. Episodic memory formation is mostly dependent on the proper function of the hippocampus. However, mechanisms of episodic memory formation, maintenance and retrieval are only beginning to be elucidated. One of the leading scientific theories about the hippocampal role in memory is indexing theory. This concept builds on the premise that hippocampal neurons are multi-synaptically bi-directionally linked with sensory and associative cortical regions. Nevertheless, it is not clear if cortical reinstating occurs on a neuro
