Visão Geral
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 protocol of self-administration is discussed, which includes description of necessary equipment and different routes of administration commonly employed. Some modified protocols used to model more complex aspects of addiction, such as progressive ratio schedule and extinction, are also explained. Finally, experiments conducted in current addiction research labs will be examined.
