The stimulus control of local enclosures and barriers over head direction and place cell spatial firing

open access: yesBrain and Behavior, 2021
Objective Head direction cell and place cell spatially tuned firing is often anchored to salient visual landmarks on the periphery of a recording environment.

Statistical and information properties of head direction cells [PDF]

open access: yesPerception & Psychophysics, 2001
The human channel capacity for identifying sensory stimuli is compared with channel capacities based on neurophysiological findings. Studies have shown that cells in the postsubiculum (PoS) and the anterior dorsal thalamus (ADN) of the rat discharge as a function of the animal's head direction in the horizontal plane.

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’

The Preferred Directions of Conjunctive Grid X Head Direction Cells in the Medial Entorhinal Cortex Are Periodically Organized. [PDF]

open access: yesPLoS 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 ...

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 ...

Head direction maps remain stable despite grid map fragmentation

open access: yesFrontiers in Neural Circuits, 2012
Areas encoding space in the brain contain both representations of position (place cells and grid cells) and representations of azimuth (head direction cells).

Rapid Spatial Reorientation and Head Direction Cells [PDF]

open access: yesThe Journal of Neuroscience, 2003
It is surprising how quickly we can find our bearings when suddenly confronted with a familiar environment, for instance when the lights are turned on in a dark room. Subjectively, this appears to occur almost instantaneously, yet the neural processes permitting this rapid reorientation are unknown.

Lesions of the head direction cell system impair direction discrimination. [PDF]

open access: yesBehavioral Neuroscience, 2019
Previous results suggest that directional information from the head direction cell circuit may inform hippocampal place cell firing when an animal is confronted with visually identical environments. To investigate whether such information might also be essential for spatial behavior, we tested adult, male Lister Hooded rats that had received either ...

Reverse Engineering and Robotics as Tools for Analyzing Neural Circuits

open access: yesFrontiers in Neurorobotics, 2021
Understanding neuronal circuits that have evolved over millions of years to control adaptive behavior may provide us with alternative solutions to problems in robotics.
