Ep165 "What's a Doom Loop & How Do You Escape It?" with Jonathan Downar
Summary
Neuroscientist David Eagleman and psychiatrist Jonathan Downer explore "doom loops," where the brain gets stuck in repetitive thoughts seen in depression, OCD, and PTSD. They discuss how these conditions stem from a failure to exit neural circuits, rather than just chemical imbalances. The episode highlights emerging treatments like Transcranial Magnetic Stimulation (TMS) and Deep Brain Stimulation, which aim to reset these circuits and restore the brain’s ability to transition between mental states.
