Nadine Burke Harris, Nucleus Accumbens, Heart Disease discussed on TED Radio Hour
Guy rise and on the show today. Hardwired ideas about how our biology and our experiences determine who we are. And before the break pediatrician Nadine Burke Harris was explaining that childhood adversity is one kind of experience that can result in severe health problems. We now understand better than we ever have before. How exposure to early adversity affects the developing brains and bodies of children, it affects areas like the nucleus accumbens, the pleasure and reward center of the brain that if implicated in substance attendance, it inhibits the prefrontal cortex which is necessary for impulse control and executive function a critical area for learning and on MRI scans we see measurable differences in the amid della the brain's fear response center. So there are real newer logic reasons, why folks exposed to high doses of adversity are more likely to engage in high risk behavior, and that's important to know. But it turns out that even if you don't engage in any high risk behavior, you're still more likely to develop heart disease, or cancer. The reason for this has to do with the hypothalamus Patou itary adrenal access, the brains and bodies stress response system that governs our fight or flight response. How does it work?.
