Dialysate levels of DA from the striatum of awake rats treated 1 week, 1 month, 6 months, or 12 months earlier with saline or METH. Excess potassium (100 mm) was included in the perfusate for 20 min starting at 0 min (horizontal bar above K+), and 100 μm amphetamine was included in the perfusate for 20 min starting at 120 min (horizontal bar aboveAmphetamine). The values shown are mean ± SEM from six or seven animals in each group. *p < 0.05 versus saline at same time point (three-way repeated measures ANOVA followed by Newman–Keuls post hoc comparisons).
