Face familiarity detection with complex synapses

This paper demonstrates that complex synapses enhance memory capacity for face familiarity detection, outperforming simple synapses in real-world recognition tasks.

Neural representational geometries correlate with behavioral differences in monkeys and recurrent neural networks

The paper shows that differences in neural representational geometry between monkeys correlate with behavioral differences and training levels, using recurrent neural networks to model these strategies.

Population dynamics underlying associative learning in the dorsal and ventral hippocampus

The paper tracks how neurons in the dorsal and ventral hippocampus update odor-outcome associations over learning phases using 2-photon calcium imaging.

Coding of social novelty in the hippocampal CA2 region and its disruption and rescue in a mouse model of schizophrenia

The paper investigates how hippocampal CA2 neurons encode social novelty and shows that disrupting this coding in a schizophrenia mouse model can be rescued by a TREK-1 antagonist.

A distributed neural code in the dentate gyrus and CA1

The paper shows that position, direction, and speed in the hippocampus are encoded by overlapping neuronal ensembles in dentate gyrus and CA1, suggesting a distributed neural code rather than single-cell specialization.

Hippocampal network reorganization underlies the formation of a temporal association memory

This study uses 2-photon calcium imaging to show that hippocampal network reorganization underlies temporal association memory formation, challenging theories of persistent activity.
