Neurocomputing, 1999
Abstract We present a model of the rat head direction cell circuit that accounts for the recently discovered bimodality and distortion observed in the tuning curves of anterior thalamic head direction cells. This model also explains why anterior thalamic head direction cells show a constant amount of anticipation across all angular velocities.

Interspike interval analysis and spikelets in presubicular head-direction cells
Journal of Neurophysiology, 2018Head-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.

A neuromorphic head direction cell system
2009 IEEE International Symposium on Circuits and Systems, 2009The head direction (HD) cell system in the brain of mammals is thought to be part of the neural circuitry supporting their spatial navigation capabilities. In this paper we present a neuromorphic VLSI system that mimics the operation of the HD system. Relying on spiking neurons and attractor dynamics, this system can be used to represent and retain the

Head direction cells in the primate pre-subiculum
Hippocampus, 1999The function of the primate hippocampus and related structures was analysed by making recordings from the hippocampus, subiculum, presubiculum, and parahippocampal gyrus in monkeys actively walking in the laboratory. Head direction cells were found in the presubiculum.

A Neuromorphic VLSI Head Direction Cell System
IEEE Transactions on Circuits and Systems I: Regular Papers, 2011The head direction (HD) cell system in the brain of mammals is thought to be part of the neural circuitry supporting their spatial navigation capabilities. In this paper we present a neuromorphic very large scale integration system that models the operation of the HD system.

Avian navigation: Head direction cells in the quail hippocampus
Current Biology, 2021Birds are experts in many behaviors akin to those in mammals that are known to involve the hippocampus, yet the avian hippocampus is still poorly understood. A new study finds head-direction cells, but not place cells, in the hippocampal formation of quails.

Heading‐vector navigation based on head‐direction cells and path integration
Hippocampus, 2008AbstractInsect navigation is guided by heading vectors that are computed by path integration. Mammalian navigation models, on the other hand, are typically based on map‐like place representations provided by hippocampal place cells. Such models compute optimal routes as a continuous series of locations that connect the current location to a goal.

Cue control and head direction cells.
Behavioral Neuroscience, 1998Previous research has shown that head direction (HD) cells in both the anterior dorsal thalamus (ADN) and the postsubiculum (PoS) in rats discharge in relation to familiar, visual landmarks in the environment. This study assessed whether PoS and ADN HD cells would be similarly responsive to nonvisual or unfamiliar environmental cues. After visual input

Calibration of the head direction network: a role for symmetric angular head velocity cells
Journal of Computational Neuroscience, 2010Continuous attractor networks require calibration. Computational models of the head direction (HD) system of the rat usually assume that the connections that maintain HD neuron activity are pre-wired and static. Ongoing activity in these models relies on precise continuous attractor dynamics.
