Rapid Spatial Reorientation and Head Direction Cells [PDF]
The 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.

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.

NEURAL MODELS OF HEAD-DIRECTION CELLS [PDF]
From Associations to Rules, 2008 After a review of the purpose and biological background of Head Direction Cells, and existing models of them, we introduce an improved neural model that integrates visual flow information with the vestibular inputs found in earlier models. Simulation results using real video inputs are presented to explore and validate the new model, the evolutionary ...

Head direction cells in a migratory bird prefer north. [PDF]
Sci Adv, 2022 Animals exhibit remarkable navigation abilities as if they have an internal compass. Head direction (HD) cells encoding the animal’s heading azimuth are found in the brain of several animal species; the HD cell signals are dependent on the vestibular nuclei, where magnetic responsive cells are present in birds.

Landmark processing by head direction cells [PDF]
, 2016 Head direction (HD) cells are neurons that increase their firing rate whenever a rat faces within a range of heading directions, irrespective of its location within the environment.

Interspike interval analysis and spikelets in presubicular head-direction cells
Journal of Neurophysiology, 2018 Head-direction (HD) neurons are thought to provide the mammalian brain with an internal sense of direction. These cells, which selectively increase their firing when the animal’s head points in a specific direction, use the spike rate to encode HD with a high signal-to-noise ratio.

Micromachines, 2022 Simultaneous monitoring of animal behavior and neuronal activity in the brain enables us to examine the neural underpinnings of behaviors. Conventionally, the neural activity data are buffered, amplified, multiplexed, and then converted from analog to ...

A Bio-Inspired 3-D Neural Compass Based on Head Direction Cells
IEEE Access, 2021 Head direction cells (HDCs) in mammals’ brains are thought to provide the sense of direction (function of a compass). They fire when the animal’s head points to a specific orientation.

Statistical and information properties of head direction cells [PDF]
Perception & 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.
