The hippocampus as a small-world cognitive map

The paper uses a geometry-aware autoencoder to analyze hippocampal activity in mice, revealing a small-world network structure that enables both local fidelity and global searchability in cognitive maps.

Ataraxis: Bridging AI Coding Assistants and Scientific Hardware

This paper introduces AO_SCPLOWTARAXISC_SCPLOW, a framework that integrates AI coding assistants with scientific hardware control, reducing setup time in experimental platforms.

Learning produces a hippocampal cognitive map in the form of an orthogonalized state machine

The paper shows that learning in the hippocampus produces orthogonalized neural representations resembling a state machine, captured by HMMs and biologically plausible networks, but not by gradient-based models.

Organizing memories for generalization in complementary learning systems

This paper introduces a neural network model of systems consolidation that optimizes memory transfer for generalization, showing how selective consolidation supports both memory and adaptive behavior.

A sparse, spatially biased subtype of mature granule cell is preferentially recruited in hippocampal-associated behaviors

The paper identifies a rare, spatially localized granule cell subtype in the hippocampus that is preferentially recruited during memory formation.
