What have single-cell recording taught us about the hippocampus and spatial memory?
What will be an ideal response?
The research began with the discovery of place cells, hippocampal neurons tuned to particular spatial locations, responding best when an animal is in a particular place and looking in a particular direction. The discovery of place cells enabled researchers to "read a rat's mind" to a limited degree. Many of the place cells also function as time cells that respond at a point in a sequence of time. Evidently, rats keep track of where they are in both space and time. Finally, an animal determines its location and direction from a combination of inputs from several populations of cells called grid cells. When an animal moves to a different environment, all the cells reorder themselves to map out the new locations.
