This study investigates whether preserved hippocampal-midbrain function during novelty and expectation processing underlies superior memory in superagers compared to typical older adults.

The paper shows that hippocampal ripples predict visual stimulus unpredictability and modulate cortical responses in humans.

The paper examines the relationship between episodic learning rate and brain structure in older adults, finding associations with hippocampal volume and white matter integrity.

This study investigates whether surprise during retrieval engages an adaptive encoding mechanism, enhancing memory for future related events through bottom-up processing.

The paper shows that violations of contextual and mnemonic expectations enhance memory by engaging pattern separation, improving discrimination of similar items.

This study uses a neural network model to show that DG and CA3 subfields of the hippocampus are more sensitive to expectation violations than CA1 during memory encoding.
