Figure 5.

Learning curves in object-in-place scene learning at each stage of the experiment (Preop, Postop1, and Postop2). Each curve shows the mean percent error on each trial over the 10-session performance tests. The left panel shows the learning curves from control monkeys, who received saline injections followed by fornix transection (CON1–3 in Table 1), and the right panel shows the learning curves from cholinergic lesioned monkeys, who received saporin injections followed by fornix transection (ACh1–3 in Table 1).
