Circuit breakers for addiction [PDF]

Internal Medicine Journal, 2007
AbstractThe phenomenon of addiction is complex, although its expression clinically is relatively straightforward. There is a series of neurophysiological changes that mediate changes in the mesolimbic and mesocortical systems which in turn lead to disturbances in reward mechanisms.
