Essentials: Erasing Fears & Traumas Using Modern Neuroscience

In this Huberman Lab Essentials episode, I explore the neuroscience
of fear and trauma and how to effectively process and eliminate
traumatic responses. I explain why successful fear treatment
requires both extinction of the old fearful response and
replacement with a new positive association—not just cognitive
reframing. I also explain how the threat reflex activates specific
circuits connecting the amygdala, prefrontal cortex, and dopamine
systems, and why detailed recounting of traumatic events
progressively reduces their physiological impact. Finally, I review
evidence-based approaches, including prolonged exposure therapy and
cognitive behavioral therapy, discuss how five minutes per day of
deliberate stress through cyclic hyperventilation can rewire fear
responses, explain the critical role of social connection in
activating neural pathways that reduce trauma, and share
supplementation options for managing anxiety. Read the episode show
