University of South Dakota associate professor of biomedical sciences Lee Baugh, Ph.D., discusses his research on the genetic predispositions involved with post-traumatic stress disorder in the second of a two part series on PTSD on the USD podcast Credit Hour.

Baugh earned his Ph.D. in brain and cognitive sciences in 2010 from the University of Manitoba. He also directs the Human Functional Imaging Core at USD.

“PTSD is a condition that we’ve known about for essentially hundreds of years ever since people have been exposed to trauma. What’s really changed about it is the way it’s framed,” Lee said. “During the days when railway travel was very common, you’d hear it referred to as 'railroad spine' because traveling the railways was so dangerous. In World War I, it was known as 'shell shock.' At its heart, it’s really a magnified response to fear stimuli that shouldn’t be there.”
