George F. Koob (born 1947) is a Professor and former Chair of the Committee on the Neurobiology of Addictive Disorders at the Scripps Research Institute [1] and Adjunct Professor of Psychology, Psychiatry, and Skaggs School of Pharmacy and Pharmaceutical Sciences at the University of California, San Diego.
Koob, Lloyd, and Mason reviewed the laboratory models approximating each stage of the model of human addiction. The binge-intoxication phase traditionally has been modeled by drug or alcohol self-administration; the psychological effects of addiction might be modeled by the increased motivation for self-administration observed in drug-dependent ...

Contemporary research in neurobiology (a branch of science that deals with the anatomy, [9] physiology, and pathology of nervous system) of addiction points to genetics as a major contributing factor to addiction vulnerability. It has been estimated that 40–60% of the vulnerability to developing an addiction is due to genetics.
The animal models of addiction are particularly useful because animals that are addicted to a substance show behaviors similar to human addicts. This implies that the structural changes that can be observed after the animal ingests a drug can be correlated with an animal's behavioral changes, as well as with similar changes occurring in humans.
Under the model of alcoholism, alcohol use disorder is viewed as chronic problem for which abstinence is required. [4] A brain disease model of addiction, based on the extent of neuroadaptation and impaired control, is main position advanced for proposing a disease model of alcohol use disorder. [5]
Surprisingly enough, Ansari and Easter found out that they share several hobbies (like two-stepping) and run in similar social circles, just on very different schedules.“He works odd shifts. And ...
Studies have proven that genetic variations and differences in our neurobiology can alter an individual's vulnerability to developing an addiction. [32] Estimates have shown that around 40%-60% of the susceptibility of an individual to develop an addiction to drugs, nicotine, and alcohol is allotted to genetic variables. [ 32 ]
