6. Athina Demertzi, PhD on the neuroscience of consciousness

In this episode, I had the pleasure of speaking with Athina Demertzi, PhD, a neuroscientist at the University of Liège who studies human consciousness, especially in patients with severe brain injuries. We discussed her fascinating work on disorders of consciousness like the vegetative and minimally conscious states, and how brain imaging techniques have advanced our understanding of these conditions. We also talked about some treatments people have proposed for these conditions, including psychedelics.
