EEG Expert Can't Explain Near Death Experience Data...

Neurologist and University of Toledo Neuroscience Researcher, Dr. John Greenfield considers the EEG data from patients with near death experience (NDE).

eeg-book21For near death experience skeptics, medical evidence of a flat EEG during an out of body experience has always been a stumbling block. After all, a brain dead patient can’t hallucinate. But, does a flat EEG really mean no brain activity?

NDE doubters have claimed activity deep inside the brain, beyond the reach of EEG instruments, must account for the complex “realer than real” experiences reported by those who briefly pass into the afterlife. Now, University of Toledo Neuroscience researcher, and EEG expert, Dr. John Greenfield explains why this claim doesn’t hold up.

“It’s very unlikely that a hypoperfused brain [someone with no blood flow to the brain], with no evidence of electrical activity could generate NDEs. Human studies as well as animal studies have typically shown very little brain perfusion [blood flow] or glucose utilization when the EEG is flat. There are deep brain areas involved in generating memories that might still operate at some very reduced level during cardiac arrest, but of course any subcortically generated activity can’t be brought to consciousness without at least one functioning cerebral hemisphere. So even if there were some way that NDEs were generated during the hypoxic state [while the brain is shut off from oxygen], you would not experience them until reperfusion [blood flow] allowed you to dream them or wake up and talk about them”, Greenfield stated.

NDE Researcher, Dr. Penny Sartori, examines memories of resuscitation by patients suffering cardiac arrest.

With near death experience cases making there way into the, New England Journal of Medicine, Journal of Psychiatry, and other major medical journals, NDE doubters have looked to the timing of patient memories as a way of explaining this unexplainable phenomena. If memories of out of body travel, and all embracing love occur after ones brush with death, NDEs may still fit within our medical science worldview.

The timing of NDE memories is the research question Dr. Penny Sartori sought to answer, “I worked in the intensive care unit and because of the nature of my job, of course, I’d come across a lot of death. And of course makes you wonder what happens when we die. For five years I gathered data, where I spoke to patients in the intensive care unit and particularly patients who’d had a cardiac arrest. When these patients revived, as soon as they were medically fit, I approached them and asked the simple question, ‘Did you have any memory of the time that you were unconscious?’”
