Figure 1.

General locomotor activity during the pre- and post-conditioning tests. The total distance traveled (A–C) and the total numbers of entries (D–F) to all three compartments were plotted over five segments to show the general locomotor and habituation. Group mean and standard errors were shown for each time segment. Animals were grouped in individual figures to show the main effect of MPH pretreatment for the pre-conditioning test (A,D) and post-conditioning test(B,E), and the main effect of the cocaine doses (C,F) at the post-conditioning test. MPH1, 2.5 mg/kg MPH once per day treatment; MPH2, 2.5 mg/kg MPH twice per day treatment.
