Figure 7. Example 4 Data.

Hippocampal neural spiking during free foraging. Four cells recorded while a rat was freely foraging in a circular environment. The x-y position at which the cell fires is denoted in red and superimposed on the path of the freely foraging rat in blue. Note that each cell tends to fire near certain locations more than others. The goal in experiments such as this one is to estimate the receptive field or “place” field of each cell based on the recorded spiking activity.
