How does the brain convert sensory information into abstract representations that can support complex behaviours? The rodent head-direction (HD) system, whose cell ensembles represent head direction in the horizontal plane, is a striking example of a “cognitive” representation without a direct sensory correlate. It can be updated by sensory inputs from different modalities, yet persists in the absence of external input. Together with cells tuned for place, the HD system is thought to be… 
The Head Direction Cell System and Behavior: The Effects of Lesions to the Lateral Mammillary Bodies on Spatial Memory in a Novel Landmark Task and in the Water Maze
TLDR
The results suggest that the LMN, and potentially the head direction cell system, are not essential for the use of visual landmarks to guide spatial behavior.

Dead Reckoning, Landmark Learning, and the Sense of Direction: A Neurophysiological and Computational Hypothesis
TLDR
A hypothesis is proposed in which the integration process is replaced by a linear associative mapping, an operation that is at least theoretically easy to implement with neurons, and visual landmarks become incorporated into the directional system, enabling the correction of cumulative error and the computation of novel, optimal trajectories between locations.
Preferential use of the landmark navigational system by head direction cells in rats.
TLDR
Results showed that when a salient, familiar cue was reintroduced to rat's environment into a position that conflicted with the cell's current firing direction, HD cells in both the ATN and the postsubiculum shifted their preferred direction to reflect their originally established orientation with this cue.

Influence of conflicting visual, inertial and substratal cues on head direction cell activity
TLDR
Results indicate that visual cues exerted a strong but incomplete control over the preferred directions of the neurons, while inertial cues had a small but significant influence, and substratal cues were of no consequence.
Angular Path Integration by Moving “Hill of Activity”: A Spiking Neuron Model without Recurrent Excitation of the Head-Direction System
TLDR
An LMN-DTN network model that consists of three populations of noisy and spiking neurons coupled by biophysically realistic synapses is built and it is found that a combination of uniform external excitation and recurrent cross-inhibition can give rise to direction-selective persistent activity.
Deciphering the hippocampal polyglot: the hippocampus as a path integration system.
TLDR
A hypothesis of how the path integration system may operate at the neuronal level is proposed, and it appears that viewpoint-specific visual information becomes secondarily bound to this structure by associative learning.

TLDR
The results suggest that extra-hippocampal structures are capable of creating and maintaining a novel representation of the animal's environmental context that shares features in common with mnemonic processes involving episodic memory that until now were assumed to require an intact hippocampus.
Head Direction Cells in Rats with Hippocampal or Overlying Neocortical Lesions: Evidence for Impaired Angular Path Integration
TLDR
The findings suggest that the hippocampus and the overlying neocortex are involved in path integration mechanisms, which enable an animal to maintain an accurate representation of its directional heading when exploring a novel environment.
Background, But Not Foreground, Spatial Cues Are Taken as References for Head Direction Responses by Rat Anterodorsal Thalamus Neurons
TLDR
Results provide a possible neurophysiological basis for observations from psychophysical experiments in humans that background, rather than foreground, cues are preferentially used for spatial orientation.
