Depth psychology. Jungian symbolism. Psychedelic drugs. Mystery religions. fMRI scans. Dream states vs. awake states. Functional connectomics. Animal consciousness. Neural correlates of the ego and the unconscious mind. All in a one-hour conversation.

Ben is joined by Robin Carhart-Harris, a researcher at Imperial College, London who conducted a study many of us have been waiting for for more than 40 years: He gave people LSD, put them in a cutting-edge fMRI scanner, and mapped how their brain connectivity changed while they were on the drug.

Here’s on the podcast to talk about that, and a whole lot more.
