TL;DR
The distinctions between drugs in the induction and expression of sensitization indicate that behavioral sensitization can arise from multiple neuroadaptations in multiple brain nuclei, not only the result of distinct molecular targets for the drugs, but may also include a differential involvement of learned associations.
Abstract
The distinctions between drugs in the induction and expression of sensitization indicate that behavioral sensitization can arise from multiple neuroadaptations in multiple brain nuclei. This is not only the result of distinct molecular targets for the drugs, but may also include a differential involvement of learned associations. It is postulated that the relatively more robust pharmacological capacity of amphetamine to release dopamine may induce a form of sensitization that is more dependent on adaptations in mesoaccumbens dopamine transmission compared with cocaine and morphine sensitization.
