Episodic memories can be thought of as sequential associations linked together by a common contextual or event representation. There has been much work examining how individual events become stabilized in memory.
Here I will present our work in humans first showing that we can measure post-encoding persistence with fMRI and show that this relates to later memory accessibility. Furthermore, we look at how multiple experiences encountered at the same time later are re-organized according to their shared features in both hippocampus and cortex, perhaps relating to the development of knowledge structures which represent related memories with overlapping neural ensembles.
