Learning accurate path integration in ring attractor models of the head direction system [PDF]
eLife, 2022 Ring attractor models for angular path integration have received strong experimental support. To function as integrators, head direction circuits require precisely tuned connectivity, but it is currently unknown how such tuning could be achieved.

Influence of sensory modality and control dynamics on human path integration [PDF]
eLife, 2022 Path integration is a sensorimotor computation that can be used to infer latent dynamical states by integrating self-motion cues. We studied the influence of sensory observation (visual/vestibular) and latent control dynamics (velocity/acceleration) on ...

Not seeing the forest for the trees: combination of path integration and landmark cues in human virtual navigation [PDF]
Frontiers in Behavioral NeuroscienceIntroductionIn order to successfully move from place to place, our brain often combines sensory inputs from various sources by dynamically weighting spatial cues according to their reliability and relevance for a given task.

A Neural Network Model for Learning 3D Object Representations Through Haptic Exploration
Frontiers in Neurorobotics, 2021 Humans initially learn about objects through the sense of touch, in a process called “haptic exploration.” In this paper, we present a neural network model of this learning process. The model implements two key assumptions.

Multi-Scale Extension in an Entorhinal-Hippocampal Model for Cognitive Map Building
Frontiers in Neurorobotics, 2021 Neuroscience research shows that, by relying on internal spatial representations provided by the hippocampus and entorhinal cortex, mammals are able to build topological maps of environments and navigate.

Interaction between path integration and visual orientation during the homing run of fiddler crabs [PDF]
Royal Society Open Science, 2017 Foraging fiddler crabs form a strict spatial relationship between their current positions and burrows, allowing them to run directly back to their burrows when startled even without visual contacts.

Size Matters: How Scaling Affects the Interaction between Grid and Border Cells
Frontiers in Computational Neuroscience, 2017 Many hippocampal cell types are characterized by a progressive increase in scale along the dorsal-to-ventral axis, such as in the cases of head-direction, grid and place cells.
