Mind Matters

Is it possible to personally alter the physical structure of your brain? On today's Mind Matters News, host Dr. Michael Egnor sits down with fellow neurosurgeon and author Dr. Lee Warren to discuss his book The Life-Changing Art of Self-Brain Surgery. Dr. Warren shares how his medical training and Christian faith collided after the tragic loss of his son. The experience helped him realize that the mind is more than just brain activity. Dr. Warren unpacks the main thrust of his book, describing self-brain surgery as the intentional practice of choosing different thoughts to physically change the brain’s structure and improve overall health. Dr. Warren has observed the effects of such self-driven change in real-time brain scans, which deliver positive results like reducing the body's stress response and promoting healing. Learn how you can alter your brain and bring about lasting positive change in your life.

On this bingecast episode of Mind Matters News, host Dr. Robert J. Marks welcomes to the podcast Dr. Mihretu Guta to discuss one of his chapters in the volume Minding the Brain titled “Mirror Neurons, Consciousness, and the Bearer Question.” Dr. Guta discusses the concept of “mirror neurons” – a type of brain cell that fires when a person observes an action being performed, as well as when the person performs the same action themselves. The properties of these neurons suggest they may play a role in empathy and understanding others’ actions. Dr. Guta explores the implications of mirror neurons to the mind-brain debate and how further study could illuminate these fascinating neural components.

On this episode of the Mind Matters News podcast, join host Robert J. Marks as he sits down with Dr. Giorgios Mappouras for a deep dive into the philosophical and technical boundaries that define the gap between human minds and silicon machines. The pair look at why the classic Turing Test is no longer a sufficient measure of machine intelligence in the age of large language models. They explore Giorgio's proposal for a more rigorous framework that can better evaluate AI's abilities.
