Séminaire - Daniele Caprioli Neuronal mechanisms of incubation of methamphetamine craving after prolonged voluntary abstinence

Abstract :

Methamphetamine addiction is characterized by high relapse rates often precipitated by exposure to drug-associated cues that provoke drug craving. In rodent studies of drug craving, cue-induced drug seeking is assessed after experimenter-imposed forced abstinence. However, in humans, abstinence is often self-imposed, or voluntary, in favor of other non-addictive alternative rewards. In the present lecture I will present a new choice-based rat model of relapse, along with its first  neurobehavioral characterization, in which Meth craving is observed after prolonged voluntary abstinence.
