<p>Cocaine addiction isn’t simply a failure of willpower — it’s the result of lasting biological changes in the brain. Researchers at Michigan State University discovered that repeated cocaine use rewires communication between the brain’s reward system and the hippocampus, the region responsible for memory. A protein called DeltaFosB builds up with continued drug use and acts like a genetic switch, altering how neurons function and strengthening the brain’s drive to seek cocaine.</p>
