With respect to sort of brain neurobiology, one of the most replicated findings we have,

sort of it's held up over time, is related to a chemical called neuropeptide Y.

So we found at Sears School that the active duty personnel who had more NPI

actually performed better as rated by the cadre when they were in interrogation stress.

For the military folks, I think that's the function of training like you're going to fight.

So there's not, you're reducing any controllable novelty in the battle space because novelty

is potentially more stressful to our brain.

Hey, welcome back to another episode of the Modern War Institute podcast.

I'm John Amble, editorial director at MWI.

And in this episode, MWI's Major Jake Moraldi talks to Dr. Charles

Morgan. Dr. Morgan is a forensic psychologist whose work at Yale University at the National

Center for Post-traumatic Stress Disorder, and with various military and government organizations,

has helped us better understand the nature of stress and psychological responses to it on the battlefield.

From a neurobiological perspective, what drives PTSD? Is there something that makes certain

people more or less susceptible? What happens inside our bodies and in our brains that impacts

the way we perform in combat? Dr. Morgan engages with these and other questions in this tremendously interesting conversation.

Before we get to it, though, as always, just a couple quick notes.

First, if you aren't yet following MWI on social media, find us on Twitter, Facebook, and LinkedIn.

It is a great way to stay up to date on the new articles, podcast episodes, and research we're releasing every day.

Second, just so you know, this episode originally aired in 2018.

And lastly, what you hear in this episode are the views of the participants and don't represent

those of West Point, the Army, or any other agency of the U.S. government.
