Neurosurgeon Michael Egnor did a recent podcast with Arjuna Das at Theology Unleashed, “where Eastern theology meets Western skepticism.” In this segment, they discuss the significance of the fact that there are aspects of the human mind that cannot be split into parts — as demonstrated by the work of Nobelist Roger Sperry (1913–1994). Here is a partial transcript and notes for the 57 minute mark to the 1 hour five minute mark: Michael Egnor: If one is to try to understand the mind in a coherent, consistent framework, one wants to have a metaphysical perspective that does the job, that makes sense. I think there are three different metaphysical perspectives that one could consider, materialist, idealist, and dualist… By Read More ›

Is there neurological evidence for the soul? What have brain experiments taught us about free will and the human person? Can you still think in a coma? Show Notes Read More ›
Roughly one in 4,000 people lacks a corpus callosum, the structure of neural fibers that transfers information between the brain’s two hemispheres. Surprisingly, the 25% who have nothing but cerebrospinal fluid do not show signs of abnormality. About half have some brain-related problems and the remaining 25% have serious problems. Researchers wanted to know, how does anyone manage to live normally without a corpus callosum to connect the two hemispheres of the brain? It turns out that the human brain goes into high gear, organizing a fix: In a study published in the journal Cerebral Cortex, neuroscientists from the University of Geneva (UNIGE) discovered that when the neuronal fibres that act as a bridge between the hemispheres are missing, the Read More ›
If you lose all four of your limbs, are you still you? Most people would say yes. What if your brain were cut into two pieces? Would you still be you? Robert J. Marks and Dr. Michael Egnor discuss splitting the brain and the research of Roger Sperry. Show Notes 00:30 | Introducing Dr. Michael Egnor, Professor of Neurosurgery and Read More ›
Patients after split-brain surgery are not split people. They feel the same, act the same, and think the same, for all intents and purposes. Materialists like Jerry Coyne focus on subtle differences and distort the big picture.
