This paper develops a transformer model to decode specific memories from human neuronal activity before and after sleep, finding differential contributions from brain regions.

The paper investigates hippocampal ripples during encoding and finds they predict clustering of recalled items, not direct recall.

The paper finds that hippocampal ripples increase before the recall of episodic memories, particularly those that are temporally and semantically clustered.

The paper investigates differences in mnemonic accuracy for 'what', 'where', and 'when' components of recently-formed episodes and finds that 'when' is least accurate and most affected by memory load.

This study shows that monkey hippocampal neurons differentiate novel from repeated naturalistic videos through firing rate changes during presentation, not delay periods, suggesting a role in familiarity-based recognition memory.

This study investigates pattern separation in monkey hippocampus by training monkeys on a visual task and analyzing neural responses to distinguish novel and similar images.
