Aaron Schurger: Neuroscience Does Not Threaten Free Will
About this episode
The Libet experiment didn't kill free will, says professor of neuroscience Aaron Schurger; the brain's "readiness potential" is simply stochastic neural noise. We then tackle consciousness's role in initiating action, the hard problem, and what it'd take for neuroscience to truly disprove our choices. If you’re interested in the topics above, I think you’ll love this podcast.
