Split Mind: The Strangest Theory in Neuroscience?

The idea that we might all have separate, undetected consciousnesses in each half of our brain supports materialism but there’s little evidence for it

A century ago, many scientists — though certainly not all — cherished the hope that science would some day show that our universe is entirely determined by laws of physics physicalism. Neuroscientists insisted, along these lines, that the mind is simply the physical processes of the brain. But neuroscience is identifying many facts that show that the mind is independent of the brain. While working on the book that neurosurgeon Michael Egnor and I are writing on neuroscience evidence for the human soul (Worthy, 2024), I learned something remarkable: Some people’s brains have been split in half (corpus callosotomy) to treat otherwise intractable epilepsy) typically continue to think normally. For people who believe that the mind is simply the buzz Read More ›

Is Consciousness a “Controlled Brain Hallucination”? No.

Anil Seth explains away consciousness away using fashionable terms like that. As a pediatric neurosurgeon, I know from clinical experience that he is wrong

Philosopher David Chalmers famously divided the problem of understanding how consciousness is related to the brain by distinguishing between the easy and hard problems of consciousness. The easy problem of consciousness is typically faced by working neuroscientists — i.e., what parts of the brain are metabolically active when we’re awake? What kinds of neurons are involved in memory? These problems are “easy” only in the sense that they are tractable. The neuroscience necessary to answer them is challenging but, with enough skill and perseverance, it can be done. The hard problem of consciousness is another matter entirely. It is this: How can first-person subjective experience arise from brain matter? How do we get an ‘I’ from an ‘it’? Compared with Read More ›
