Fear, Reward, and The Bottle: An Update to My Column on Neurogenetics
In May I wrote in Discover about a major experiment in neuroscience. Ahmad Hariri, a neuroscientist at Duke, is gathering lots of data from hundreds of college students–everything from genetic markers to psychological profiles to fMRI scans. He hopes that the Duke Neurogenetics Study, as he’s dubbed it, will reveal some of the ways in which the variations in our genes influence our brain circuitry and, ultimately, our personality and behavior.
Hariri plans to collect data from over 1000 people, but he and his colleagues are already starting to analyze the hundreds of students they’ve already examined to look for emerging patterns. In the open-access journal Biology of Mood and Anxiety Disorders, they’ve just published some of their
