Researchers have identified, for the first time, long-term changes in the brain circuitry of methamphetamine-addicted mice that can explain why the craving of addiction is so stubborn and long-lived. The research could lead to more effective treatments for addiction to methamphetamine and related drugs.Nigel Bamford and colleagues published their findings in the April 10, 2008, issue of the journal Neuron, published by Cell Press.
