11、 have long ago weeded it out of the population: if its hard to drive safely under the influence, imagine trying to run from a saber-toothed tiger or catch a squirrel for lunch. And yet, says Dr. Nora Volkow, director of NIDA and a pioneer in the use of imaging to understand addiction, “the use of dr
12、ugs has been recorded since the beginning of civilization. Humans in my view will always want to experiment with things to make them feel good. “Thats because drugs of abuse co-opt the very brain functions that allowed our distant ancestors to survive in a hostile world. Our minds are programmed to
13、pay extra attention to what neurologists call salience-that is, special relevance. Threats, for example, are highly salient, which is why we instinctively try to get away from them. But so are food and sex because they help the individual and the species survive. Drugs of abuse capitalize on this re
14、ady-made programming. When exposed to drugs, our memory systems, reward circuits, decision-making skills and conditioning kick in-salience in overdrive-to create an all consuming pattern of uncontrollable craving. “Some people have a genetic predisposition to addiction,“ says Volkow. “But because it
15、 involves these basic brain functions, everyone will become an addict if sufficiently exposed to drugs or alcohol. “That can go for nonchemical addictions as well. Behaviors, from gambling to shopping to sex, may start out as habits but slide into addictions. Sometimes there might be a behavior-spec
16、ific root of the problem. Volkows research group, for example, has shown that pathologically obese people who are compulsive eaters exhibit hyperactivity in the areas of the brain that process food stimuli-including the mouth, lips and tongue. For them, activating these regions is like opening the f
17、loodgates to the pleasure center. Almost anything deeply enjoyable can turn into an addiction, though.Of course, not everyone becomes an addict. Thats because we have other, more analytical regions that can evaluate consequences and override mere pleasure seeking. Brain imaging is showing exactly ho
18、w that happens. Paulus, for example, looked at drug addicts enrolled in a VA hospitals intensive four-week rehabilitation program. Those who were more likely to relapse in the first year after completing the program were also less able to complete tasks involving cognitive skills and less able to ad
19、just to new rules quickly. This suggested that those patients might also be less adept at using analytical areas of the brain while performing decision-making tasks. Sure enough, brain scans showed that there were reduced levels of activation in the prefrontal cortex, where rational thought can over
20、ride impulsive behavior. Its impossible to say if the drugs might have damaged these abilities in the relapsers-an effect rather than a cause of the chemical abuse-but the fact that the cognitive deficit existed in only some of the drug users suggests that there was something innate that was unique
21、to them. To his surprise, Paulus found that 80% to 90% of the time, he could accurately predict who would relapse within a year simply by examining the scans.Another area of focus for researchers involves the brains reward system, powered largely by the neurotransmitter dopamine. Investigators are l
22、ooking specifically at the family of dopamine receptors that populate nerve cells and bind to the compound. The hope is that if you can reduce the effect Of the brain chemical that carries the pleasurable signal, you can loosen the drugs hold.(分数:10.00)(1).According to Dr. Nora Volkow, the use of dr
