"Nature" Editorials - Science has a gambling problem

Researchers and government agencies pay too little attention to pathological gambling...There is insufficient research on what can tip a gambler towards destructive addiction.This must change! PDF version



Disordered gambling is a major societal problem with high costs to the subjects involved. Animal models may help in understanding and preventing gambling-related problems. Data show that some (lab) animals may have gambling-like profiles, yet we need few additional steps towards models of disordered gambling. Read all

  Adolescence appears to be a period of heightened propensity to develop addictions but the biological factors that increased vulnerability were not known. New research carried out in rats and published in the Journal of Neuroscience provides important clues. Relative to adults, adolescent rats took cocaine more readily, were more sensitive to lower doses, showed greater escalation of cocaine intake, and were less susceptible to increases in work they had to do to get the drug.

 Adolescent rats also showed increased activity of dopamine neurons, a feature known to be associated with increased drug self-administration behaviour. Dopamine is essential or drug-induced reward. The results highlight behavioural and biological markers of heightened addiction liability during adolescence
