#206 – Anil Seth on the predictive brain and how to study consciousness

"In that famous example of the dress, half of the people in the world saw [blue and black], half saw [white and gold]. It turns out there’s individual differences in how brains take into account ambient light. Colour is one example where it’s pretty clear that what we experience is a kind of inference: it’s the brain’s best guess about what’s going on in some way out there in the world. And that’s the claim that I’ve taken on board as a general hypothesis for consciousness: that all our perceptual experiences are inferences about something we don’t and cannot have direct access to." —Anil Seth

In today’s episode, host Luisa Rodriguez speaks to Anil Seth — director of the Sussex Centre for Consciousness Science — about how much we can learn about consciousness by studying the brain.

Links to learn more, highlights, and full transcript.

They cover:

  • What groundbreaking studies with split-brain patients and blindsight have already taught us about the nature of consciousness.
  • Anil’s theory that our perception is a “controlled hallucination” generated by our predictive brains.
  • Whether looking for the parts of the brain that correlate with consciousness is the right way to learn about what consciousness is.
  • Whether our theories of human consciousness can be applied to nonhuman animals.
  • Anil’s thoughts on whether machines could ever be conscious.
  • Disagreements and open questions in the field of consciousness studies, and what areas Anil is most excited to explore next.
  • And much more.
