As we've learned in KPCC reporter Annie Gilbertson's series "Teaching Through Trauma," poor students in Los Angeles are facing some major hurdles.

One recent study found that four in five students at high-poverty schools experience multiple traumatic episodes. And research shows that stress and trauma can actually change kids' brains, making it more difficult for them to learn and do well in school.

Dr. Cara Wellman has studied how chronic stress impacts the brain. She's a professor of neuroscience and psychology at Indiana University in Bloomington, Indiana and she joined Take Two for more on how stress can change the brain.
