Today, we're going to talk about how psychedelics alter our perception of reality and what that says about... reality!

Welcome to part two of our conversation with Stanford anesthesiologist and psychedelics researcher Boris Heifets!

Last time, we talked with Boris about the question of why psychedelics help people with mental health disorders.

This week, we're going to dive into a different question, which is to explore how psychedelics work in the brain. How are they able to alter something as fundamental as our perceptions of reality — and could understanding these effects teach us about the nature of our everyday perceptions?
