Cells that fire in sequence during a theta cycle form a sweep. Three examples are shown. (Top) Top panels show track. Current position of rat is marked by arrowhead, and it is at this position that the sweep shown below occurs. Different cells active during the sweep have place field centers marked by the colored dots. (Bottom) The spikes of different cells during a theta cycle (start to end). Cells are positioned on the y axis according to the position of their place field centers. In these examples, activity sweeps represent positions along the path ahead of the animal.
