Resetting the Alcoholic Brain (Audio)
Adron Harris, director of the Waggoner Center for Alcoho and Addiction Research, and his team mapped the differences in gene expression between an alcoholic's brain and a non-alcoholic's brain. They found that, as a person becomes dependent on alcohol, thousands of genes in their brains are turned up or down, like a dimmer switch on a lightbulb, compared to the same genes in a healthy person's brain.
