Circuit-specific reorganization of hippocampal-entorhinal-prefrontal subnetworks supports memory recall across the lifespan

The paper examines how memory recall circuits reorganize across the lifespan in mice, showing a shift from hippocampal to broader cortical networks involving the entorhinal cortex.

Phase-locking of hippocampal CA3 neurons to distal CA1 theta oscillations selectively predicts memory performance

This study shows that CA3 neuronal spiking synchronized with distal CA1 theta oscillations predicts memory performance in a non-spatial recognition task.

Remembering the gist of an event over a lifetime depends on the hippocampus

This study shows that CA1 is necessary for gist memory retrieval regardless of memory age, while CA3 is required for memory precision in a time-dependent manner.

Recognition memory: familiarity signals increase selectively in the lateral entorhinal cortex following hippocampal lesions

This study shows that hippocampal lesions increase lateral entorhinal cortex activity during familiarity judgments, suggesting HIP modulates LEC in recognition memory.
