Dr. Ben-Shahar is interested in the neuroadaptations that result from, and mediate, cocaine addiction. For this purpose, she uses a model for drug addiction in which some rats show compulsive drug-taking behavior reminiscent of the pattern seen in human cocaine addicts and some show the stable controlled pattern of drug taking behavior reminiscent of the recreational use in human drug-users. Dr. Ben-Shahar investigates the neuronal changes that are associated with these different patterns of drug-taking behavior using immunohistochemistry, receptor autoradiography, immunoblotting, micro-PET imaging, and intracranial injections. In order to find what are the general motivational changes that are associated with drug use and addiction, these rats are also tested on various behavioral tests that explore motivational change.
