Directionally tuned signals in mouse visual and subicular cortex during passive rotation

This study compares directional activity in mouse visual and subicular cortex during passive rotation, finding differences in how visual cues influence their directional tuning.

Dynamics of thalamic directional coding under vestibular imbalance

This study investigates how head direction cells adapt to unilateral vestibular loss in rats, revealing cell-type-specific changes in directional coding.

Structured navigation emerges from self-guided spatial learning in freely moving common marmosets

This study shows that common marmosets develop structured, memory-guided navigation through self-guided experience in a foraging task, forming flexible yet predictable movement patterns.

The statistical power of three monkeys

The paper presents a statistical framework to evaluate the power of experiments with few animals, showing that using three animals and accepting results from two improves statistical power and reduces risk.

Influence of sensory modality and control dynamics on human path integration

This study investigates how sensory modality and control dynamics affect human path integration in virtual reality, finding that vestibular signals alone are insufficient without sustained acceleration.

Spatial modulation of hippocampal activity in freely moving macaques

This study examines hippocampal activity in freely moving macaques, finding that spatial representations are dominated by head orientation and eye movements rather than place or grid coding.

Two functionally distinct Purkinje cell populations implement an internal model within a single olivo-cerebellar loop

The paper shows two Purkinje cell populations in the cerebellum work together in a single olivo-cerebellar loop to implement an internal model of the otolith organs.

A gravity-based three-dimensional compass in the mouse brain

This study identifies a three-dimensional gravity-based neural compass in the mouse brain that integrates pitch, roll, and azimuth orientation.

Multiplexed code of navigation variables in the anterior limbic system

The paper uses a multimodal model to analyze how neurons in specific brain regions of mice encode navigational variables during foraging, revealing new coding patterns in the anterior thalamus and retrosplenial cortex.

Simple spike dynamics of Purkinje cells in the macaque vestibulo-cerebellum reflect sensory prediction error

The paper examines Purkinje cell dynamics in the macaque vestibulo-cerebellum, finding that two cell types encode tilt velocity and translation acceleration, which represent sensory prediction error for updating sensory estimates.

A re-interpretation of the experimental data of Shinder and Taube \"Three-dimensional Tuning of Head Direction Cells in Rats\", Journal of Neurophysiology 121(1), 2019.

This paper re-analyzes Shinder and Taube's 2019 study on head direction cells in rats, showing their data supports 3D tuning models rather than their 1D conclusion.

Neuronal thresholds and correlations in the peripheral vestibular system during rotation discrimination

This study measures neuronal and behavioral thresholds during rotation discrimination in macaques, finding similar thresholds and significant neuronal correlations but no trial-by-trial activity-behavior link.

The brain compass: a perspective on how self-motion updates the head direction cell attractor

This paper proposes a framework explaining how self-motion cues update head direction cell attractors and discusses context-dependent firing differences and three-dimensional compass properties.

A unified internal model theory to resolve the paradox of active versus passive self-motion sensation

The paper constructs a Kalman filter model to explain how a single internal model of head motion processes motor commands and sensory signals during both active and passive movements.
