My guest is Dr. Christof Koch, PhD, a pioneering researcher on the topic of consciousness, an investigator at the Allen Institute for Brain Science and the chief scientist at the Tiny Blue Dot Foundation. We discuss the neuroscience of consciousness—how it arises in our brain, how it shapes our identity and how we can modify and expand it. Dr. Koch explains how we all experience life through a unique “perception box,” which holds our beliefs, our memories and thus our biases about reality. We discuss how human consciousness is changed by meditation, non-sleep deep rest, psychedelics, dreams and virtual reality. We also discuss neuroplasticity (rewiring the brain), flow states and the ever-changing but also persistent aspect of the “collective consciousness” of humanity.
