FIGURE 3.

Representative response profiles seen in the homing pigeon hippocampal formation. (A) Path cells have a characteristic high firing rate when the animal is traversing between goal locations (red boxes) but less response at goal locations (blue boxes). (B) Location cells have their highest firing rates when in a localized area near food bowls. The pattern pictured corresponded to a place-like cell. (C) Arena-off cells are presumably context-dependent and fire while in the holding area (in this arena, in the NW corner) but have reduced firing while exploring the arena. (D) Pattern cells have multiple regions of high firing in multiple areas of an open arena that appear to be clustered around the arena edges.
