Robinson has maintained a research program focusing on the psychological and neurobiological basis of addiction, especially the persistent effects of repeated psychostimulant drug use on behavior and neurobiology, and with his colleague Kent C. Berridge he has also contributed highly cited theoretical articles on the role of incentive ...
Anne Lingford-Hughes is a British psychiatrist who is Professor of Addiction Biology at Imperial College London. She works on addictions at the Central and North West London NHS Foundation Trust . Her research uses neuroimaging and pharmacology to understand the neurobiology of addiction.
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.
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 ]
One form of behavioral neuropharmacology focuses on the study of drug dependence and how drug addiction affects the human mind. Most research has shown that the major part of the brain that reinforces addiction through neurochemical reward is the nucleus accumbens. The image to the right shows how dopamine is projected into this area.
