Flexible cue anchoring strategies enable stable head direction coding in both sighted and blind animals

open access: yesNature Communications, 2022
Vision plays an important role in the head direction cell system in animals. Here the authors recorded from head direction cells in rd1 mice that show retinal degeneration at 1 month, and find that they use smell cues to maintain stable HD tuning.

Towards cognitive navigation: A biologically inspired calibration mechanism for the head direction cell network

open access: yesJournal of Automation and Intelligence, 2023
To derive meaningful navigation strategies, animals have to estimate their directional headings in the environment. Accordingly, this function is achieved by the head direction cells that were found in mammalian brains, whose neural activities encode one’

Persistent Neural Activity in Head Direction Cells [PDF]

open access: yesCerebral Cortex, 2003
Many neurons throughout the rat limbic system discharge in relation to the animal's directional heading with respect to its environment. These so-called head direction (HD) cells exhibit characteristics of persistent neural activity. This article summarizes where HD cells are found, their major properties, and some of the important experiments that ...

Spatial navigation: head direction cells are anchored by gravity. [PDF]

open access: yesCurr Biol, 2013
Thalamic neurons that signal an animal's direction of heading are crucial for spatial navigation. Both directional coding and flexible use of spatial memory are upended, however, when a rat has to find its way while upside down.

Three-dimensional tuning of head direction cells in rats. [PDF]

open access: yesJ Neurophysiol, 2019
Head direction (HD) cells fire when the animal faces that cell’s preferred firing direction (PFD) in the horizontal plane. The PFD response when the animal is oriented outside the earth-horizontal plane could result from cells representing direction in the plane of locomotion or as a three-dimensional (3D), global-referenced direction anchored to ...

Encoding of Head Direction by Hippocampal Place Cells in Bats [PDF]

open access: yesThe Journal of Neuroscience, 2014
Most theories of navigation rely on the concept of a mental map and compass. Hippocampal place cells are neurons thought to be important for representing the mental map; these neurons become active when the animal traverses a specific location in the environment (the “place field”). Head-direction cells are found outside the hippocampus, and encode the

Allocentric directional processing in the rodent and human retrosplenial cortex [PDF]

open access: yes, 2014
Head direction cells in the rodent brain have been investigated for a number of years, providing us with a detailed understanding of how the rodent brain codes for allocentric direction.

Video data for the cognitive mapping process of NeuroBayesSLAM system

open access: yesData in Brief, 2020
Simultaneous localization and mapping (SLAM), which addresses the problem of constructing a spatial map of an unknown environment while simultaneously determining the mobile robot's position relative to this map, is regarded as one of the key ...

Home, head direction stability and grid cell distortion [PDF]

open access: yesJournal of Neurophysiology, 2019
Abstract The home is a unique location in the life of humans and animals. Numerous behavioral studies investigating homing indicate that many animals maintain an online representation of the direction of the home, a home vector. Here we placed the rat’s home cage in the arena, while recording neurons in the animal’s parasubiculum and ...
