Episode 4: Quantum Physics, Plant Medicines & the Study of Consciousness Edward James & Joachim Keppler

Dr. Joe Tafur and Natasha Pentin spoke with Edward James, Ph.D., and Joachim Keppler, Ph.D. Edward brings expertise across pharmacology, psychedelic compounds, and biochemistry. Joachim is a quantum field theory physicist, devoted to the study of consciousness and uncovering its fundamental mechanisms. With their colleagues, they published a paper together in 2022 about DMT, ayahuasca plant medicine, and human consciousness. We had many messages asking for an episode about quantum physics…so here it is! We discuss two different theories of consciousness: the biological processes model that is explained by biological or neurophysiological processes versus the idea that the universe is pervaded by an ubiquitous field of consciousness (which corresponds with the laws of physics). In other words, viewing the brain as a filter, and that it can somehow couple with the larger consciousness. Edward and Joachim explain how related work may eventually lead to further understanding of the therapeutic benefits of psychedelic medicines. Thanks for listening!
