Cocaine Makes Brains Worse at Learning from Mistakes
Cocaine addicts may have more difficulty recognizing the effects of bad decisions, because the drug may actually impair the circuits in the brain responsible for recognizing and predicting loss, according to a new study. "The human species is guided by the prospect of maximizing rewards and minimizing costs," said Rita Goldstein, one of the scientists on the research team. "When you are taking the drug again, you are getting that high, and you are getting those positive responses, but you are not getting the ability to predict the negative ones," said Muhammad Parvaz, a researcher involved with the study.
