NC4Touch is an open-source rodent touchscreen apparatus that enables affordable, customizable, and high-throughput behavioral testing in mice and rats.

The paper shows that theta frequency reflects internal path-integration gain errors during navigation, providing a method to estimate hidden cognitive variables through physiological oscillations.

The paper investigates how head direction and CA1 place cells recalibrate path-integration gain during navigation, showing synchronized recalibration during movement but distinct dynamics during head-scanning.

The paper introduces the Omniroute maze, a high-throughput rodent navigation system that automates route configuration, sensory cues, and reward delivery for behavioral experiments.

The paper introduces an open-source rodent gate system for customizable maze tasks, enabling affordable and robust behavior control.

The paper demonstrates that optic flow can recalibrate path integration in hippocampal place cells using a closed-loop virtual reality system.

This paper introduces a single-camera, marker-based system for high-accuracy 6-degree-of-freedom head tracking of rodents, achieving accuracy comparable to multi-camera systems.

The paper studies electrosensory interactions in cave and surface dwelling electric fish, finding sustained frequency differences and long-distance interactions despite expected jamming avoidance.

This study shows that the path integration gain in hippocampal place cells is a plastic variable that can be recalibrated by persistent conflict between self-motion cues and external landmarks.
