The addicted brain

drugs.jpgDoes an alcoholic have a disordered brain or a flawed character? The latest issue of Nature Neuroscience contains a special focus supplement on addiction that is freely available online for the next three months.

The Focus contains the latest reviews and commentaries on the neuroscience of addiction, including discussion of the changes caused by drugs to brain circuits and synapses; the cortical and sub-cortical brain areas that mediate the reinforcing effect of drugs; how drugs affect people’s decision making, tipping the balance in their consideration of immediate rewards weighed against future costs; the genetic influences on personality traits that predispose people to addiction; as well as consideration of the social stigma of addiction and the difficulties of developing effective treatments.
