Dopamine (DA) in medial prefrontal cortex is crucial in extinction of aversive or appetitive experiences. Although attention has been mostly focused on the infralimbic area of prefrontal cortex, a role of the prelimbic (PL) area has been envisaged pointing to DA transmission in the extinction of drug conditioned behavior. Evidence shows that DA exerts its action also via both D1 and D2 receptor subtypes. Here we investigated the effects of D1 and D2 receptor agonist microinfusion in the PL cortex of C57BL/6J mice on expression and extinction of amphetamine-induced conditioned place preference (CPP), in order to ascertain the effects of selective vs concomitant receptor subtypes stimulation. SKF38393 and Quinpirole were used at doses not impairing expression of amphetamine-induced CPP on the day of infusion. Acute infusion of each agonist alone did not affect extinction in subsequent days in comparison with Vehicle-treated mice, while concomitant infusion of both agonists produced a clear-cut advance of extinction of preference for the compartment previously paired with amphetamine. These results show that concomitant stimulation of D1 and D2 receptors in PL is required to foster extinction suggesting a synergic action between receptors or a heteromeric receptor involvement.
