Erasing Fears & Traumas Based on the Modern Neuroscience of Fear

In this episode, I discuss fear and trauma, including the neural circuits involved in the "threat reflex" and how specific experiences and memories come to activate that system. I also discuss how our body is involved in trauma and fear. First, I describe the logic of fear mechanisms and how "top-down" processing-- meaning connections from the parts of the brain that assign meaning to our feelings, are involved in fear and erasing fears and traumas. Then I discuss what successful fear and trauma treatment must include and consider various treatments for whether they meet that standard, such as EMDR, Cognitive Behavioral Therapy, Ketamine, other drug-assisted therapies, and more. I also review new data on how 5 minutes per day of deliberate, self-imposed stress can erase fear and depression. And I review the role that social connection plays in erasing or maintaining fears by activating specific molecular pathways in the brain and body. Finally, I review supplementation with over-the-counter compounds for their effects on anxiety and fear and when to take them, if at all.  For the full show notes, visit hubermanlab.com.
