Driven to Drink: Brain Enzyme Linked to Alcohol Dependency

The ability to resist drinking alcohol when the urge strikes may partly rely on a certain enzyme in the brain, and alcohol use and dependency may reduce the levels of this enzyme, a new study in rats finds. In the new study, researchers discovered that restricting the brain's production of an enzyme — called Prdm2 and found in the brain's frontal lobes — disrupted rats' impulse control. Although scientists have long suspected that brain activity in the frontal lobes was connected to
