The rat hippocampus contains place cells whose firing is location-specific. These cells fire only when the rat enters a restricted region of the environment called the firing field. In this review, we examine the sensory information that is fundamental to the place cell system for producing spatial firing. While visual information takes precedence in the control of firing fields when it is available, local (olfactory and/or tactile) cues combined with motion-related cues can permit stable… 
Sensory Determinants of Hippocampal Place Cell Firing Fields
TLDR
The existence of place cells, the impairments in most spatial tasks caused by hippocampal damage and the clear correlation between the state of the hippocampal EEG and locomotor behavior together strongly suggest that the hippocampus plays a critical role in the processing of spatial information.
Place cells, neocortex and spatial navigation: a short review
TLDR
It is concluded that place cells, together with head direction cells, provide information useful for spatially guided movements, and thus provide a unique model of how spatial information is encoded in the brain.
Goal-Related Activity in Hippocampal Place Cells
TLDR
It is proposed that place cells provide both a geometric representation of the current environment and a reflection of the rat's expectancy that it is located correctly at the goal, and may participate in a neural network allowing the rat to plan accurate trajectories in space.
Stability and variability of place cell activity during behavior: Functional implications for dynamic coding of spatial information
TLDR
An explanatory framework is proposed in which place cell activity at different timescales could be viewed as a series of dynamic attractors nested within each other, and some examples from recent research work are provided showing that this problem is far from being trivial.
Hippocampal functional organization: A microstructure of the place cell network encoding space
TLDR
It is shown that in animals confined to a small part of a maze, principal cells in the CA1/CA3 subfields of the dorsal hippocampus immunoreactive (IR) for Zif268 adhere to a 'cluster-type' organization.
Spatial discrimination of visually similar environments by hippocampal place cells in the presence of remote recalibrating landmarks
TLDR
The results suggest that the place cell system is able to form a specific spatial representation for all sectors, so that the rat knows, at any time, in which sector it is currently located.
Spatial Navigation.
TLDR
The presence of all the spatially specific firing patterns in the hippocampus and the related neural circuits during the path integration and map-based navigation support such a notion that in essence, path integration is the same allocentric space perception provided with only idiothetic inputs.
Dynamically detuned oscillations account for the coupled rate and temporal code of place cell firing
TLDR
Realistic patterns of rate and temporal coding emerged and were found to be inseparable and may have implications on the robustness of information coding in place cell firing and on the ways information is processed in structures downstream to the hippocampus.
Directing Neural Representations of Space
The study of the neurobiology of spatial navigation provides a neural model for a complex form of learning that is likely to be highly conserved across evolution. Single cell recordings from rats as
Is there a pilot in the brain? Contribution of the self-positioning system to spatial navigation
TLDR
This review focuses on the issue of how self-localization is performed in the hippocampal place cell map and hypothesizes that sequential reactivation of place cells could participate in the resetting of self- localization under specific circumstances and in learning a new environment.

Influences of vestibular and visual motion information on the spatial firing patterns of hippocampal place cells
TLDR
Hippocampal place cells show location-specific firing as animals locomote in an environment that is influenced by movement-related information, since this is the only available, ongoing indicator of current location when external orienting cues are not present.
Firing properties of hippocampal neurons in a visually symmetrical environment: contributions of multiple sensory cues and mnemonic processes
TLDR
It is concluded that place cells are influenced both by the immediate sensory configuration and by internal neural states related to earlier experience in the environment.
The positional firing properties of medial entorhinal neurons: description and comparison with hippocampal place cells
TLDR
The positional firing of MEC cells is more “sensory bound” than hippocampal cells, and the ability to discriminate different environments, while present in the hippocampus, is not yet present in its input from MEC.
Spatial Firing of Hippocampal Place Cells in Blind Rats
TLDR
This study studied place cell activity in early blind rats and found that these rats had place cells very similar to those recorded from sighted rats, suggesting that early vision is not necessary for normal firing of hippocampal place cells.
Spatial and behavioral correlates of hippocampal neuronal activity
The firing rate of hippocampal neurons in rats was related both to spatial location and to multiple behavioral variables as rats performed 2 kinds of tasks that rely on hippocampal function: a
Directional control of hippocampal place fields
TLDR
Control of the rat’s internal directional sense is gained, independently of other cues, to see whether manipulating this sense could, by itself, produce a corresponding alteration in place field orientation, and it opens the door to psychophysical exploration of the sensory basis of the direction sense.
A model of hippocampal function
TLDR
A model of hippocampal function is presented in which the firing rate maps of cells downstream of the hippocampus provide a ''population vector'' encoding the instantaneous direction of the rat from a previously encountered reward site, enabling navigation to it.

TLDR
It appears that the orienting influence of a visual cue on place fields can be either strengthened or weakened relative to the idiothetic cues, depending on the experience of the rat.

The results suggest that hippocampal unit activity predicts the animal's future location on a short time scale.
Computer simulation of hippocampal place cells
TLDR
A model in which pyramidal cells are the output layer of a competitive-learning, pattern-classification device and patterns of environmental stimuli as viewed by a computerized “rat” from various locations within a simulated environment is presented.
