Active Locomotion Increases Peak Firing Rates of Anterodorsal Thalamic Head Direction Cells
TLDR
Results are consistent with the hypothesis that the level of locomotor activity provides a state-dependent modulation of the response magnitude of AD HD cells, and could result from diffusely projecting neuromodulatory systems associated with motor state.Abstract:
Head direction (HD) cells discharge selectively in macaques, rats, and mice when they orient their head in a specific (“preferred”) direction. Preferred directions are influenced by visual cues as ...read more

The Head Direction Signal: Origins and Sensory-Motor Integration
TL;DR: V Vestibular information appears critical for generating the directional signal, but motor/proprioceptive and landmark information are important for updating it.

The anterior thalamus provides a subcortical circuit supporting memory and spatial navigation.

TL;DR: The electrophysiological properties of cells in the anterior thalamic nuclei are discussed with an emphasis on their role in spatial navigation and neuroanatomical and functional relationships between the ATN and hippocampal formation are described.

The subiculum: what it does, what it might do, and what neuroanatomy has yet to tell us
TL;DR: It is argued that there is a dorso‐ventral segregation of function within the subiculum: the dorsal component appears principally concerned with the processing of information about space, movement and memory, whereas the ventral component appears to play a major regulatory role in the inhibition of the HPA axis.

Spatial cognition in bats and rats: from sensory acquisition to multiscale maps and navigation
TL;DR: The experimental findings and theoretical models are reviewed that provide insight into the mechanisms that link sensory systems to spatial representations and to large-scale natural navigation.

Theta rhythm of the hippocampus: subcortical control and functional significance.
TL;DR: It is suggested that the hippocampus receives two main types of input: theta rhythm from ascending brain stem- diencephaloseptal systems and information bearing mainly from thalamocortical/cortical systems.

Head-direction cells recorded from the postsubiculum in freely moving rats. I. Description and quantitative analysis
TL;DR: A new cell type is identified that signals the animal's head direction in its environment as well as the range of head-direction angles over which discharge was elevated and the location of the animal within the cylinder had minimal effect on directional cell firing.

Head-direction cells recorded from the postsubiculum in freely moving rats. II. Effects of environmental manipulations.
TL;DR: The results demonstrate that specific visual cues in the environment can exert control over the preferred firing direction and indicate that head- direction cell firing is not a simple sensory response to visual cues, but rather represents more abstract information concerning the animal's spatial relationship with its environment.

Representation of Spatial Orientation by the Intrinsic Dynamics of the Head-Direction Cell Ensemble: A Theory
TL;DR: The model offers a specific one-dimensional example of a computational mechanism in which a truly world-centered representation can be derived from observer-centered sensory inputs by integrating self-motion information.

Spatial firing patterns of hippocampal complex-spike cells in a fixed environment
TL;DR: In this article, a TV/computer technique was used to simultaneously track a rat's position in a simple apparatus and record the firing of single hippocampal complex-spike neurons.
