Figure 2.
Systemic administration of the system xc inhibitor sulfasalazine dose-dependently reduces extracellular glutamate levels in the prefrontal cortex. This graph depicts extracellular glutamate levels in the prefrontal cortex before and after an injection of vehicle (1 ml/kg, IP; N=7) or sulfasalazine (4–16 mg/kg, IP; N= 7–8/group). * p<.05 indicates a significant reduction relative to vehicle-treated subjects in post-injection extracellular glutamate levels in the prefrontal cortex (one-sided Dunnett’s T).
