Understanding the empirical rules that regulate alterations of hippocampal firing fields will enhance our understanding of hippocampal function. The current study sought to extend previous research in this area by examining the effect of substituting a new stimulus for a familiar stimulus in a familiar environment. Hippocampal place cells were recorded while rats chased food pellets scattered onto the floor of a cylindrical apparatus with a white cue card affixed to the apparatus wall. Once a… 
Failure of Centrally Placed Objects to Control the Firing Fields of Hippocampal Place Cells
TLDR
The results indicate that the failure of stimulus control in Experiment 1 must be attributable to the arrangement of the objects and not to the nature of the object themselves, and is in line with behavioral studies that show that it is very difficult to teach rats to locate food relative to landmarks inside the behavioral arena.
Place cells, head direction cells, and the learning of landmark stability
TLDR
It appears that the strength of cue control over place cells and head direction cells depends on the rat's learned perception of the stability of the cues.
Inertial, Substratal and Landmark Cue Control of Hippocampal CA1 Place Cell Activity
TLDR
Evidence is provided for contributions of inertial as well as substratal and landmark information to hippocampal spatial representations in relation to environmental landmarks.
Independent coding of connected environments by place cells
TLDR
The results suggest that the hippocampus holds a set of independent maps for each box, and that each specific map is activated mainly according to the rat's current sensory environment.
Contribution of multiple sensory information to place field stability in hippocampal place cells
TLDR
The results suggest that rats are not able to rely on only movement‐related information to maintain a stable place representation, visual input is necessary for the firing of a large number of cells, and olfactory information can be used to compensate for the lack of visuospatial information.
Place fields of rat hippocampal pyramidal cells and spatial learning in the watermaze
TLDR
It is suggested that place fields in the watermaze are largely controlled by the same factors as on dry land, in spite of the differences in kinaesthetic and vestibular input.
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.
Discordance of spatial representation in ensembles of hippocampal place cells
TLDR
It is indicated that hippocampal neurons independently encode distinct subsets of the cues in a complex environment, although processing within the hippocampal network may actively reduce the simultaneous representation of conflicting orientation information.
Fear conditioning alters neuron-specific hippocampal place field stability via the basolateral amygdala
TLDR
This work tested the hypothesis that a rat's perception of an environment could be changed by introducing an auditory fear-conditioned stimulus to a previously neutral environment, inducing plasticity of hippocampal place fields and showed neuron-specific conditional plasticity for actively firing hippocampusal place cells.
Hippocampal place cells can develop distinct representations of two visually identical environments

TLDR
The findings indicate that hippocampal place cells not only can develop distinct representations of two visually identical environments but also can selectively reactivate either one of these representations depending on the rat's recent experience.

TLDR
The response of place cells to changes in the animal's environment was investigated using the techniques set out in the preceding paper and the firing pattern of a cell in an apparatus of one shape could not be predicted from a knowledge of the firing patterns in the other shape.
Hippocampal place cells: stereotypy and plasticity
TLDR
Findings suggest hippocampal place cell firing, although highly influenced by spatial and directional features of the environment, can readily change under conditions in which significant stimuli are added or removed from those locations.
Place units in the hippocampus of the freely moving rat
TLDR
The results suggest that place units were not responding to a simple sensory stimulus nor to a specific motor behavior, and are interpreted as strong support for the cognitive map theory of hippocampal function.

TLDR
Rats were pretrained to perform an operant task in a straight-line shuttle box for food reward and then transferred to a T-maze (requiring similar behavior), showing specific spatial firing immediately in 10 of 12 cases.
Selective impairment of learning and blockade of long-term potentiation by an N-methyl-D-aspartate receptor antagonist, AP5
TLDR
It is reported that chronic intraventricular infusion of D, L-AP5 causes a selective impairment of place learning, which is highly sensitive to hippocampal damage7, without affecting visual discrimination learning,which is not8 and suggest that NMDA receptors are involved in spatial learning, and add support to the hypothesis that LTP is involved in some, but not all, forms of learning.
