Question

Quizplus · Accepted Answer

Brower's research suggests that chronic drug use can result in the depletion of neurotransmitters involved in stress and reward, which may lead to changes in brain patterns and activity that contribute to addiction. Choice A is incorrect as research has shown that addiction is indeed linked to changes in brain activity. Choice B is incorrect as familial history can increase the risk of addiction, but it is not the only factor involved in changes in brain patterns due to drug use. Choice D is incorrect as there is a growing body of research that supports the relationship between addiction and changes in brain activity, although the exact mechanisms are still being studied.
