WebIn a series of studies we have found that there is considerable individual variation in the extent to which reward cues acquire incentive motivational properties. Some rats, called sign-trackers (STs) are especially prone to attribute incentive salience to reward cues, relative to others (goal-trackers, GTs). WebTHE INCENTIVE SENSITIZATION THEORY A stunning anecdote often arising from clinical settings is that as drugs become wanted more and more, they may become liked less and less. This is compatible with the idea that the basic brain mecha-nisms of reward “liking” and reward “wanting” are dissociable. In fact, the incentive sensitization theory
WebAug 30, 2024 · This theory suggests that repeated use of illicit drugs induces neuroadaptations leading to enduring sensitization of dopamine systems with subsequent hyperreactivity in response to drug cues and a pathological degree of incentive salience, manifesting as a disproportionate motivation to pursue the drug ( 16, 18, 19 ). WebIncentive sensitization refers to particular neurobiological changes in brain mesolimbic dopamine systems and in related structures belonging to the same larger brain circuit that mediate the psychological function of incentive salience (“wanting”).
WebAbstract The incentive-sensitization theory (IST) addresses the questions of why addicts crave drugs, why drug craving persists after long periods of abstinence, and if drug craving is attributable to liking drugs. IST posits that addictive drugs share the ability to enhance mesotelencephalic dopamine (DA) neurotransmission. WebFour major tenets of the incentive-sensitization view are discussed. These are: (1) Potentially addictive drugs share the ability to produce long-lasting adaptations in neural systems. (2) The brain systems that are changed include those normally involved in the process of incentive motivation and reward.
