429:. One important aspect of episodic memory is the spatial context in which the event occurred. Hippocampal place cells have stable firing patterns even when cues from a location are removed and specific place fields begin firing when exposed to signals or a subset of signals from a previous location. This suggests that place cells provide the spatial context for a memory by recalling the neural representation of the environment in which the memory occurred. By establishing spatial context, place cells play a role in completing memory patterns. Furthermore, place cells are able to maintain a spatial representation of one location while recalling the neural map of a separate location, effectively differentiating between present experience and past memory. Place cells are therefore considered to demonstrate both pattern completion and pattern separation qualities.

information is any kind of spatial input that might indicate a distance between two points. For example, the edges of an environment might signal the size of the overall place field or the distance between two points within a place field. Metric signals can be either linear or directional. Directional inputs provide information about the orientation of a place field, whereas linear inputs essentially form a representational grid. Contextual cues allow established place fields to adapt to minor changes in the environment, such as a change in object color or shape. Metric and contextual inputs are processed together in the
226:, meaning that they are defined with respect to the outside world rather than the body. By orienting based on the environment rather than the individual, place fields can work effectively as neural maps of the environment. A typical place cell will have only one or a few place fields in a small laboratory environment. However, in larger environments, place cells have been shown to contain multiple place fields which are usually irregular. Place cells may also show directionality, meaning they will only fire in a certain location when travelling in a particular direction.

Furthermore, the place cells in these models have unstable representations of space, and cannot learn stable representations for new environments as well as place cells in healthy mice. The hippocampal theta waves, as well as the gamma waves, that influence place cell firing, for example through phase precession, are also affected.

designed to provide a subject with spatial information. Recent findings, such as a study showing that place cells respond to non-spatial dimensions, such as sound frequency, disagree with the cognitive map theory. Instead, they support a new theory saying that the hippocampus has a more general function encoding continuous variables, and location just happens to be one of those variables. This fits in with the idea that the hippocampus has a predictive function.

in color or shape of an object. This suggests that place cells respond to complex stimuli rather than simple individual sensory cues. According to the functional differentation model, sensory information is processed in various cortical structures upstream of the hippocampus before actually reaching the structure, so that the information received by place cells is a compilation, a functional derivative, of different stimuli.

Contrarily, the CA3 place cells are show increased plasticity in aged subjects.

One possible cause of these changes in plasticity may be increased reliance on self-motion cues.

path, connection between place fields are strengthened due to plasticity, causing subsequent place fields to fire more quickly and causing place field expansion, possibly aiding young rats in spatial memory and learning. However, this observed place field expansion and plasticity is decreased in aged rat subjects, possibly reducing their capacity for spatial learning and memory.
274:. Upon entering a place field, place cells will fire in bursts at a particular point in the phase of the underlying theta waves. However, as an animal progresses through the place field, the firing will happen progressively earlier in the phase. It is thought that this phenomenon increases the accuracy of the place coding, and aids in plasticity, which is required for learning.

Place fields are extremely specific, as they are capable of remapping and adjusting firing rates in response to subtle sensory signal changes. This specificity is critical for pattern separation, as it distinguishes memories from one another.

In some cases place cells show directionality, meaning they will only fire in a location when the subject is travelling in a particular direction.

Remapping refers to the change in the place field characteristics that occurs when a subject experiences a new environment, or the same environment in a new context. This phenomenon was first reported in 1987, and is thought to play a role in the memory function of the hippocampus. There are broadly

These units were cells that fired in a particular place in the environment, the place field. They are described as having a low resting firing rate (<1 Hz) when a rat is not in its place field, but a particularly high firing rate, which can be over 100 Hz in some cases, within the place

Aged rats further show a high instability in their place cells in the CA1 region. When introduced to the same environment several times, the hippocampal map of the environment changed about 30% of the time, suggesting that the place cells are remapping in response to the exact same environment.

Furthermore, the pattern completion exhibited by place cells is symmetric, because an entire memory can be retrieved from any part of it. For example, in an object-place association memory, spatial context can be used to recall an object and the object can be used to recall the spatial context.
