Genes that modulate stress response identified

A Baylor University researcher claim to have discovered certain genes that modulates stress responses, which could cause some people to take drugs and consume alcohol. Dr Doug Matthews, professor of psychology and neuroscience at Baylor, has found a small section on chromosome one that is responsive to a particular type of stress in animal models. He then identified the genes in this region that could be responsible for the behavioural response to stress, like alcohol consumption.
