This study investigates how reward influences hippocampal spatial maps by separating its effects on map usage and structure through a two-pathway model.

RONI decomposes time-varying functional connectivity into dynamic drivers using Riemannian filtering on symmetric positive semidefinite matrices, applied to neural recordings.

This study shows that auditory cortical networks maintain stimulus representations after sensory input ends in both awake and sleeping mice, with different decay patterns in wakefulness and sleep.

This paper introduces a unified recurrent network model that co-emerges grid and place cells without supervision or pre-existing spatial-cell representations, reproducing experimental observations.

The paper shows that spatial remapping in the hippocampal formation follows low-dimensional geometric transformations across environments.

This paper proposes a system-level theory of MEC-HC wiring to explain how grid and place cell patterns enable cue-triggered goal retrieval and path planning, validated through simulations.

The paper examines whether hippocampal cells encode time or distance during treadmill experiments and finds that cell encoding depends on the type of task.

The paper investigates representational drift in neural networks and finds that learning occurs in three phases with sparsification during slow implicit regularization.

The paper shows that experience, not time, drives representational drift in hippocampal place cells during repeated exposure to familiar environments.

This study identifies place cells in the hippocampus of flying barn owls that represent spatial location and flight direction during flight.

The paper identifies head-direction cells in the hippocampal formation of Japanese quails, showing their directional tuning and stability during navigation.

The paper analyzes grid cell firing patterns during hippocampal inactivation, finding maintained synchrony despite loss of grid patterns.

This study quantifies head-direction cell drift in rat pups before and after eye-opening, finding that drift follows a random walk before eye-opening and is reduced afterward, suggesting path integration and visual correction.
