Behavioral reinforcement induced by the rewarding feelings following substance use sometimes leads to addiction, which is demonstrated by increased self-administration. Drug self-administration studies in rodents model human behavior during drug abuse. These models are useful in understanding the neurobiological behavior of addiction in order to help scientists discover new treatments for drug dependence. This video reviews the concepts underlying self-administration studies. A general...

Cue reactivity is conceptualized as sensitivity to cues linked with drug-taking experiences that contribute to craving and relapse in abstinent humans. Cue reactivity is modeled in rats by measuring attentional orientation toward drug-associated cues that results in appetitive approach behavior in a cue reactivity test following self-administration and forced abstinence.

Animal models of relapse, known as reinstatement procedures, have been used extensively to study the role of stress in relapse to drug seeking. Here, we report on a method for inducing the reinstatement of cocaine seeking in laboratory rats via acute exposures to mild, intermittent electric footshock.

FAQs
Cocaine blocks dopamine, norepinephrine, and serotonin transporters, increasing extracellular levels of these monoamines in brain reward pathways. This neurochemical change can strengthen the association between an operant response and cocaine delivery, making response patterns useful for examining reinforcement. Pharmacology researchers therefore connect behavioral measures with cocaine’s effects on multiple neurotransmitter systems rather than dopamine alone.
Defined schedules of reinforcement determine how an operant response produces cocaine delivery and help separate response performance from motivation. By examining response rates under different schedules, researchers can assess how strongly the drug maintains behavior and how effort relates to cocaine access. These comparisons provide a structured way to characterize abuse-related responding across experimental conditions.
Dose effects indicate how changing the amount of delivered cocaine influences operant responding. Researchers can compare response patterns across doses to evaluate reinforcing strength and identify conditions associated with greater or lesser drug-maintained behavior. Interpreting these relationships alongside response rates and motivation measures helps distinguish changes in cocaine’s behavioral impact from simple differences in experimental exposure.
Cues paired with cocaine delivery can acquire behavioral significance and contribute to cue-driven seeking. In this model, researchers can assess how cocaine-associated stimuli influence responding and examine behavioral processes relevant to relapse. This focus extends analysis beyond direct drug reinforcement by addressing how learned environmental or procedural signals may sustain drug-seeking behavior after the original drug experience.
A typical experiment combines an operant response, such as lever pressing, with cocaine delivery through an intravenous catheter. Researchers apply a defined reinforcement schedule and record response rates, dose effects, motivation, or cue-driven seeking. Together, these components create controlled conditions for linking an observable behavior with drug exposure and for comparing behavioral outcomes across experimental designs.
The model supports studies of cocaine’s reinforcing properties and the neurobiology associated with addiction-related behavior. It also provides a framework for evaluating potential treatments and identifying factors that influence relapse or compulsive drug seeking. Because researchers can quantify responding, motivation, dose effects, and cue-related behavior, the approach connects pharmacological mechanisms with measurable behavioral outcomes.
