Place cells literally encode location in the sense that by looking at the firing of a population of place cells, one can tell to within a few centimeters where the animal is.
The place cell representation of space is different from other spatial representations in the brain, many of which can be thought of as capturing the relationship between individual stimuli and the body or some part of it (i.e., egocentric representations).
Cells with properties similar to place cells have recently been discovered in the human hippocampus, so one might be expect it to play a similar role in spatial memory and navigation.

 JSMF - 1998 McDonnell - Pew Program in Cognitive Neuroscience
The fact that hippocampal "place cells" only fire in cell-specific locations is the basis of the idea that the hippocampus encodes and stores a cognitive map of space that animals use to solve complex spatial problems.
Place cells have almost never been recorded in conditions where the individual contributions of exteroception and interoception (allocentric and idiothetic information, respectively) to spatial firing can be assessed although this conceptual distinction is a major issue in the hippocampal place learning literature.
Experiments are proposed to simultaneously study place cells and the rat's behavior during three novel tasks in which place cells and the rat's spatial knowledge can be objectively assessed.

 .......::The DBZGT Place::....... (Cell Saga)
Created through synthesizing cells from all the great fighters into a single computer-enhanced android he has the strength and abilities of all the great fighters including Goku, Frieza, Vegeta, Gohan and many others.
While Cell has the power and abilities of all of the great fighters, his ultimate form will not be available until he can absorb Androids 17 and 18.
But Cell is devious, and through some crafty trickery manages to sneak up on the unsuspecting Android 17 and absorb him.

 The Cosyne meeting   (Site not responding. Last check: 2007-11-04)
This replay of place cell firing ensembles is thought to contribute to the consolidation of the associated memories within the hippocampus and to their transfer to neocortical long-term stores (reviewed in (Hobson and Pace-Schott 2002)).
Place cell firing in the hyperpolarizing theta troughs may facilitate depotentiation of synaptic connections involved in place cell ensembles encoding familiar environments in order to prevent saturation of the network and allow encoding and storage of new information.
Thus, along the length of the cell, there is a depolarization shift and a phase shift in the effect of the theta rhythm drive on the cell membrane wherein the somatic membrane potential oscillates out-of-phase with distal dendritic membrane potentials.

The cell may then be rotated by using a second data point to define the rotation.
This command places a cell on a linear element, and allows it to be rotated dynamically.
The cells will be placed at a rotation equal to the direction of the element at the point of offset, plus the active angle value.

 The Logic Class: Part 2 - Placement
The placement of a cell's children may not be changed once it is placed, unless the layout is transformed in a predefined manner.
Positional placement is the term used for placing a cell at a certain numerical location within a layer of hierarchy.
Relational cell placement is the ability to place a cell relative to another based on its width, height, and location.
