Figure 2.

Effects of DPAT on the routes of travel in sham and NAc lesion rats. The routes of travel are shown as path plots for a representative rat with a sham lesion (left column) and NAc lesion (right column) that was treated with saline (Sal) (top row) or DPAT (bottom row); the selected rat has a distance of travel value closest to the group mean. Locomotor trajectories during the entire 55 min session are shown, and each line represents a trajectory of locomotion; the density of trajectory lines corresponds to the amount of locomotion. Gray squares indicate locations of the four objects in the open field.
