Drug addiction: Neuro-Behavioral Approach ChanMee Bae University of Washington, Seattle PSYCH 448F Autumn2015 Abstract In this paper, I am going to summarize how chronic drug use affects the function of the brain and how this leads to the aberrant behavioral manifestations of addiction. (Volkow Li, 2005) A view of drug addiction has been changed from the ‘choices’ of the addicted individuals to the dysfunction of brain. The drug addiction may be regarded as the disease of the brain reward system. This system, closely related to the system of emotional arousal, is located predominantly in the limbic structures of the brain. (Vetulani, 2001) Within decades, the researchers got variety results about the underlying mechanism about drug addiction, however, factoring out how the drug addiction works is complex. We need to consider social and genetic mechanisms about the reasoning of drug addiction. It is fundamental to see how mechanisms and brain circuits are involved in the drug addiction for the future treatment and research.
