This study shows that rats using path integration for navigation show better generalization to novel situations compared to those using visual landmarks.

This study shows that hippocampal-dependent navigation can be insensitive to outcome revaluation, suggesting it supports habitual-like behavior in a spatial task.

The paper investigates how uncertainty modulates neural coding of choice and outcome in orbitofrontal (OFC) and secondary motor cortex (M2) during reward learning, finding differential roles in encoding under varying uncertainty levels.

This study shows that hippocampal place cell remapping occurs when rats remember aversive shocks but not when they forget them or encounter neutral stimuli.

The paper introduces a miniature microscope for high-resolution neural imaging in freely behaving rats, capable of imaging over 1000 neurons in the hippocampus and 2000 in the cortex.

The paper develops E-Scope, a tool for simultaneous multimodal recordings in freely behaving mice, revealing cerebellar and ACC activity patterns during social behavior.

DeCalciOn is a hardware system for real-time decoding of in vivo calcium imaging data, enabling closed-loop feedback experiments with millisecond latency.

This study investigates how theta oscillations in ACC and OFC affect accuracy and speed in reward learning, finding ACC inhibition impairs reversal learning while OFC theta remains unaffected.

This study uses chemogenetics and calcium imaging in rats to show that anterior cingulate cortex (ACC) discriminates between reward options, influencing effort-based decisions.

The paper examines how septal and striatal neurons respond to hippocampal sharp-wave ripple events in rats, finding differential excitatory and inhibitory responses and phase relationships with theta rhythm.

The paper shows that neural spike trains encode position and velocity through conjugate firing rate and co-firing rate codes, obeying an uncertainty principle similar to physics.

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.

The paper investigates spatial theta cells in rats to explore how temporal phase codes anchor spatial representations to external reference frames through burst synchronization and competitive learning.
