Pioneering research on brain functions by the eminent neurosurgeon Wilder Penfield provides scientific evidence for the existence of a spirit.
A few decades ago Dr. Penfield was attempting to identify the source of epileptic seizures by stimulating regions of patients’ brains. His did this by exposing the brain and delivering mild electric currents (shocks) to the conscious patient's surface neocortex. By this process he hoped to identify areas of the brain that triggered epileptic seizures. If the seizure location in a patient could be identified he would consider removing the tissue to prevent future seizures. By repeatedly stimulating brain regions in conscious patients and noting the effects, Penfield was able to construct a remarkably detailed map of localized functions in the brain, a map showing which areas of the brain controlled sensations and movements in the body.
In all his work on searching for epileptic trigger sites, Penfield noticed something very interesting. He noted that he could not locate the mind, the thing that regulates conscious decision making, reasoning, sentience, and agency.
When Penfield carried out his investigations, patients would report all sorts of sensations, memories, and movements, but these were things that happened to the patients. You see, his electrode could not stimulate patients to make a choice, to believe something, or to reason, the very things associated with the human mind.
When Penfield began his studies of the human brain, he had hoped to discover how the brain causes the mind, something that we are continually reminded of by atheists (i.e., there is no agentic mind/spirit, just brain neuronal activity). However, because no one has been able to find the physical areas of the brain that control the mind, we are left to wonder, where is the mind?
