The free podcast version of Brain Science Podcast 67 is now available. It is an interview with German philosopher Thomas Metzinger, author of The Ego Tunnel: The Science of the Mind and the Myth of the Self and Being No One. Dr. Metzinger argues that any credible model for how the brain generates the mind must incorporate unusual human experiences, such as so-called out of body experiences (OBE), and psychiatric conditions. In this interview we explore how OBE and virtual reality experiments shed light on how the brain generates the sense of self that characterizes normal human experience.
