Intrinsic Bipolar Head‐Direction Cells in the Medial Entorhinal Cortex [PDF]
Advanced ScienceHead‐direction (HD) cells are a fundamental component in the hippocampal‐entorhinal circuit for spatial navigation and help maintain an internal sense of direction to anchor the orientation in space. A classical HD cell robustly increases its firing rate

Retrosplenial and postsubicular head direction cells compared during visual landmark discrimination [PDF]
Brain and Neuroscience Advances, 2017 Background: Visual landmarks are used by head direction (HD) cells to establish and help update the animal’s representation of head direction, for use in orientation and navigation.

A Positioning Method Based on Place Cells and Head-Direction Cells for Inertial/Visual Brain-Inspired Navigation System [PDF]
Sensors, 2021 Mammals rely on vision and self-motion information in nature to distinguish directions and navigate accurately and stably. Inspired by the mammalian brain neurons to represent the spatial environment, the brain-inspired positioning method based on multi ...

Head direction cells use a head-referenced dual-axis updating rule in 3D space [PDF]
Communications BiologyHead direction (HD) cells, comprising a compass signal for the brain’s spatial map, may update their firing during 3D movement by using a ‘dual axis’ (DA) rule that sums head rotation around a local axis and local-axis rotation around the gravity axis ...

The head-direction signal is generated from two types of head direction cells in brainstem nuclei [PDF]
Nature CommunicationsHead direction (HD) cells discharge based on an animal’s directional heading. Computational models propose that a ring-attractor network across the connections between the lateral mammillary (LMN) and dorsal tegmental nuclei (DTN) underlies the signal’s ...

Nucleus reuniens of the thalamus contains head direction cells [PDF]
eLife, 2014 Discrete populations of brain cells signal heading direction, rather like a compass. These ‘head direction’ cells are largely confined to a closely-connected network of sites.

Non-rhythmic head-direction cells in the parahippocampal region are not constrained by attractor network dynamics [PDF]
eLife, 2018 Computational models postulate that head-direction (HD) cells are part of an attractor network integrating head turns. This network requires inputs from visual landmarks to anchor the HD signal to the external world.

The Preferred Directions of Conjunctive Grid X Head Direction Cells in the Medial Entorhinal Cortex Are Periodically Organized. [PDF]
PLoS ONE, 2016 The discovery of speed-modulated grid, head direction, and conjunctive grid x head direction cells in the medial entorhinal cortex has led to the hypothesis that path integration, the updating of one's spatial representation based on movement, may be ...
