Post-Learning Reactivation of Memories for Naturalistic Continuous Experiences

This study shows that memories of complex narrative events are spontaneously reactivated during rest, but reactivation is linked to gist-like recall rather than strengthening episodic memory details.

LLM-powered automatic scoring tools for memory recall

This paper introduces an LLM-powered pipeline for automatically scoring free recall of naturalistic stimuli, achieving high agreement with human raters and low cost.

Key moments in naturalistic events synchronize neural activity patterns and dominate memory reinstatement

The paper shows that key moments in naturalistic events synchronize neural activity across individuals and are overrepresented in memory reinstatement.

Evidence for shallow cognitive maps in schizophrenia

This study investigates whether schizophrenia impairs cognitive map formation, finding that individuals with SZ focus more on simple visual features and less on abstract planning-relevant features during decision-making tasks.

A content-based representational scaffold for naturalistic event memories

The paper shows that different brain networks represent specific event components during viewing and memory retrieval, with generalization across contexts and people.

Representations of complex contexts: A role for hippocampus

This study investigates how different hippocampal subfields represent item-context binding during memory retrieval using fMRI and voxel pattern similarity analyses.

Intrinsic Functional Connectivity in the Default Mode Network Predicts Mnemonic Discrimination: A Connectome-based Modeling Approach

This study uses connectome-based modeling to show that intrinsic DMN connectivity predicts mnemonic discrimination, with stronger associations in younger adults.

Building bridges: the hippocampus constructs narrative memories across distant events

This study shows that the hippocampus integrates distant events into a narrative structure during memory formation and recall.

Organization of cortico-hippocampal networks in the human brain

The paper identifies cortico-hippocampal networks in the human brain using resting-state fMRI data, revealing the DMN and MTN and their roles in memory.

The ANTs Longitudinal Cortical Thickness Pipeline

The paper introduces an ANTs-based longitudinal cortical thickness pipeline and demonstrates its effectiveness in analyzing ADNI-1 data for detecting structural brain changes over time.

Anterolateral entorhinal-hippocampal imbalance in older adults disrupts object pattern separation

This study identifies hypoactivity in the anterolateral entorhinal cortex in older adults, linked to impaired object pattern separation, without changes in the posteromedial entorhinal cortex.
