And most importantly, all of the research assistants, neurosurgeons and epilepsy patients who contributed their time and effort to these massive datasets that make research like this possible.

I’d like to thank @fuentemilla.bsky.social for writing an illuminating commentary that fits our little episode into the broader context of memory consolidation research www.nature.com/articles/s41... and our generous reviewers who greatly improved the paper with their insightful comments
Memory consolidation accelerates - Nature Neuroscience
A new study challenges the classic view of memory consolidation as a delayed, offline process by showing that neural reactivation, which is crucial for memory consolidation, occurs rapidly during awak...

In addition, they corroborate cognitive theories about the role of study-phase retrieval and covert rehearsal, linking behavioral memory phenomena to their neural substrates.

Our analyses revealed that spontaneous reinstatement of item-related neural activity during encoding intervals was a significant predictor of subsequent recall.
This suggests that consolidation-like mechanisms may occur continuously—not just during post-encoding rest.

By analyzing intracranial EEG recordings from two large datasets (N>200 in each study), we investigated the effects of reactivating item-related neural activity while studying other items on a list.

In contrast, cognitive theories of memory suggest that retrieval/rehearsal processes can strengthen prior memories even while encoding ongoing perceptual experience.

In the classic view of systems consolidation, the hippocampus strengthens previously encoded memories by spontaneously reactivating cortical activity during offline periods (such as sleep or rest) when the brain isn’t under continuous memory encoding demands.
