Behavioral apparatus and journey types.A, A 27-cm-high, 32 × 27 cm moveable cardboard box was mounted on a 184 × 8 cm linear track. The box was moved to one of five possible locations along the tack (box 1–box 5). A small food cup was mounted in the box, and another cup was permanently mounted at the opposite end of the track (goal). The rat was trained to exit the box and run to the goal (outbound journey). As the rat approached the goal, the box was shifted to a new location. After consuming the reward at the goal, the rat returned to the box (inbound journey). During the subsequent outbound journey, the box was shifted to a new location. B, The five types of outbound journeys (box1 out–box5 out). C, The five types of inbound journeys (box1 in–box5 in).
