Why Pioneer Neurosurgeon Wilder Penfield Said the Mind Is More Than the Brain

He gave three lines of reasoning, based on brain surgery on over a thousand patients

Michael Egnor points out that Penfield offered three lines of evidence: His inability to stimulate intellectual thought during brain operations, the inability of seizures to cause intellectual thought, and his inability to stimulate the will. … So he concluded that the intellect and the will are not from the brain. Which is precisely what Aristotle said.

Some People Think and Speak with Only Half a Brain

A new study sheds light on how they do it

A range of neuroscience research findings is more readily explained by assuming that some aspects of thought–– abstract intellectual thought and free will–– are immaterial.

Do We Actually Remember Everything?

Neuroscience evidence suggests that our real problem isn’t with remembering things but finding our memories when we need them

One of a pioneer neurosurgeon’s cases featured a patient who could, unaccountably, speak ancient Greek. The explanation was not occult but it was surely remarkable for what it shows about memory.

Four Researchers Whose Work Sheds Light on the Reality of the Mind

The brain can be cut in half, but the intellect and will cannot, says Michael Egnor. The intellect and will are metaphysically simple

Neurosurgeon Michael Egnor was featured in a short film as a supplement to the Science Uprising series. There, he mentions four researchers who have shed light on the non-material mind nature of our minds: Wilder Penfield (1891–1976): Some of the earliest evidence came from neurosurgeon Wilder Penfield, who was the pioneer in epilepsy surgery in the mid 20th century. Penfield operated on over a thousand epilepsy patients while they were awake (under local anesthesia), and he stimulated their brains with electrodes in order to identify epileptic regions for surgical resection. He carefully recorded their responses to stimulation. In his book Mystery of the Mind, (1975) Penfield noted: “When I have caused a conscious patient to move his hand by applying…

Does brain stimulation research challenge free will?

If we can be forced to want something, is the will still free?
The materialist interpretation of Reilly’s work is a misunderstanding of what the research actually shows. The stimulations did not evoke complex abstract intentions and acts—the patients didn’t reflexively decide to do integral calculus or donate to Amnesty International. Read More ›
