The hippocampal place cells are a highly multimodal class of neurons, receiving information from many different sensory sources to correctly localize their firing to restricted regions of an environment. Evidence suggests that the sensory information is processed upstream of the hippocampus, to extract both angular and linear metric information, and also contextual information. These various kinds of information need to be integrated for coherent firing fields to be generated, and the present… 
Landmark processing by head direction cells
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. Their

Hippocampal place cells are topographically organized, but physical space has nothing to do with it
TLDR
It is suggested that there is a topographical organization in hippocampal place cells, but the topographical map formed is not a map of the physical space, but around an abstract, multidimensional space containing the receptive fields of place cells.
Robust path integration in the entorhinal grid cell system with hippocampal feed-back
TLDR
This paper sets up the model of a mobile agent equipped with the entorhinal representation of idiothetic and allothetic information and simulated its place learning in a virtual environment, and shows that the continuous feed-back from the integrated hippocampal place representation is able to stabilize the grid cell code.
Tactile modulation of hippocampal place fields
TLDR
The results demonstrate that tactile information is integrated into place cells at least in a tactile‐enriched arena and when other sensory cues are not available.
The representation of space in the brain
The Representation of Three-Dimensional Space in Fish
TLDR
Behavior experiments on pelagic fish are described, which suggest that fish, like mammals, have a higher order representation of space that assembles incoming sensory information into a neural unit that can be used to determine position and heading in three-dimensions.
Anisotropic encoding of three-dimensional space by place cells and grid cells
TLDR
It seems that grid cell odometry (and by implication path integration) is impaired or absent in the vertical domain, at least when the rat itself remains horizontal, suggesting that the mammalian encoding of three-dimensional space is anisotropic.

Context‐specific acquisition of location discrimination by hippocampal place cells
TLDR
It is found that the acquired information did not transfer to the new context, suggesting that the context inputs and the acquired inputs must interact somewhere upstream of the place cells themselves, thus explaining the context specificity of the new learning.
Heterogeneous Modulation of Place Cell Firing by Changes in Context
TLDR
It is demonstrated, for the first time, that there is a heterogeneous input by contextual inputs into the hippocampus, and a model of contextual remapping of place cells is proposed in which the geometric inputs are selectively activated by subsets of contextual stimuli.
Behavioral correlates of the distributed coding of spatial context
TLDR
Two naturalistic measures of context processing in rats are used to explore how rats responded to contextual novelty and to relate this to the behavior of place cells, suggesting that heterogeneous context encoding by place cells may function to allow the flexible assignment of associations to contexts.
Do hippocampal pyramidal cells signal non‐spatial as well as spatial information?
TLDR
It is concluded that, contrary to the claims of its detractors, the cognitive map theory is still the theory of hippocampal function that is most clearly specified, makes the most testable predictions, and for which there is the strongest experimental support.
Modeling place fields in terms of the cortical inputs to the hippocampus
TLDR
A model of place‐cell firing is presented that makes quantitative predictions about specific place cells' spatial receptive fields following changes to the rat's environment and can be extended to make behavioral predictions regarding spatial memory.
The global record of memory in hippocampal neuronal activity
TLDR
Training rats to perform the same recognition memory task in several distinct locations in a rich spatial environment found that the activity of many hippocampal neurons was related consistently to perceptual, behavioural or cognitive events, regardless of the location where these events occurred, indicating that non-spatial events are fundamental elements of hippocampal representation.

TLDR
The experiments suggest that hippocampal place cells are part of a perceptual system, and conclude that place cells reveal that the hippocampal mapping system also has properties expected of a perceptions system.
Dissociation of the geometric and contextual influences on place cells
TLDR
A model of color-induced remapping in which place cells respond not simply to walls, but to walls of a specific color is suggested, which suggests a spatial shift of the firing location of place cells should occur only after changes to those aspects of the environment that convey spatially localizing information to the cells.
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.
