TL;DR
Results suggest that dopaminergic nerve terminals in nucleus accumbens are necessary for both the acquisition and maintenance of d-amphetamine self-administration.
Abstract
Control rats initiate self-administration of d-amphetamine and achieve stable injection rates within 7-10 days. Rats in which dopamine nerve terminals in nucleus accumbens were destroyed by bilateral microinjections of 6-hydroxydopamine (6-OHDA) did not initiate self-administration of d-amphetamine when tested for as long as 19 days. In rats previously trained to self-administer d-amphetamine, 6-OHDA injections into nucleus accumbens abolished d-amphetamine self-administration. These results suggest that dopaminergic nerve terminals in nucleus accumbens are necessary for both the acquisition and maintenance of d-amphetamine self-administration.
