Dr. Karl Deisseroth: Understanding & Healing the Mind | Huberman Lab Podcast #26

Psychedelics

The exploration of psychedelics in psychiatry presents both promising opportunities and significant risks. Karl Deisseroth emphasizes the need for rigorous study of these compounds, such as LSD and psilocybin, which alter the perception of reality in precise ways. He notes, "We have to see these as opportunities...study in the laboratory" 1. Andrew Huberman discusses MDMA's unique effects, highlighting its potential in treating trauma and PTSD by fostering a sense of connectedness 2. The therapeutic potential lies in the brain's ability to learn from these altered states, potentially offering new models for understanding and treating mental health conditions 3.

   

Research

Research into psychedelics reveals their profound impact on brain functions and perceptions. Deisseroth explains how these substances can alter the brain's hypothesis generation, allowing for new ways of constructing reality, which might aid in treating conditions like depression 3. He describes dissociation as a common experience in trauma, where the sense of self separates from the body, a phenomenon studied using ketamine in mice 4. Optogenetics has enabled researchers to replicate these dissociative states, providing insights into the brain's circuitry and potential therapeutic targets 5.
