“The interview is a fascinating look into the research occuring at the Center for Genetics and Behavioral Health, a collaboration between USD and the Avera Institute for Human Genetics,” said Michael Ewald, the podcast host. “These organizations are on the forefront of studying how genetics play a part in disorders like PTSD and hopefully, one day, developing effective treatments and prevention.”

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.”
