In this episode, we welcome back Dr. Andrew Gallimore to explore the content of his new book 'Reality Switch Technologies: Psychedelics as Tools for the Discovery and Exploration of New Worlds'.

We discuss how the brain builds an experiential world model from patterns of information at the neural level; how all of those worlds are correlated with specific neural patterns; how we can disturb that neural pattern to encounter new worlds; essentially, using psychedelic molecules to explore alternate worlds.

We explore how different classes of psychedelics affects the brain differently and thus switch us to different potential worlds, focusing specifically on the neural and world-switching effects of classical psychedelics, tropane alkaloids, and ketamine.

We also explore why the brain doesn't care if its models are true, only if their adaptive; how perception of reality flows from conceptual hypothesis down, not from sensory information upwards; the self-model and its disintegration (ego death); we talk about schizophrenia and hearing voices; and about how every experience is "real" but not all experience is accurately mapped to our environment.
