“That won’t happen,” Sarah said. “We’ll be monitoring you every moment.”
“What if you have a power failure?”
“We have generators that’ll kick in instantly,” she said. “Believe me, you’ll be fine.”
He took refuge in the promise of those tawny brown eyes. “And what about side effects—my memory, my ability to think…?”
“There are none,” Luria said. “Your memory will return. You’ll remember family, friends, your own name, language. Your cognitive powers will be normal. Think of it like a Novocain shot. An hour later, all sensations are back.”
“But while I’m under I’ll be brain-dead.”
“No, while you’re under you could pass for brain-dead. Your brain cells will still be healthy and alive, just silent.”
“And then what?”
“Then we wake you and ask you about any experience you may have had.”
“You mean like moving down a tunnel toward a light, angels or whatever.”
“That’s the prototypical notion, though the experience may be entirely different.”
“But if I’m flatlined, how can I remember experiencing anything?”
“Excellent question,” Dr. Luria said. “If you do have an NDE, those areas of the brain where the neuroelectrical activity takes place will inform other areas of your brain once you’re awake. In other words, your experience will be a kind of residual memory once your whole brain is in synchronicity again.”
Were their manners not so sober and serious, he would have thought they were joking. “This doesn’t even sound like something scientists investigate.”
“You’re right,” Luria said. “In spite of all the fascinating claims in books and the popular press, nobody has ever demonstrated if the phenomenon is real or fantasy. And one reason is that all NDE claims are untestable reports of people who survived heart attacks and accidents et cetera. But here, we conduct NDE experiments under controlled scientific conditions.”
“Of course,” Stern interjected, “we could end up discovering that it’s all in the head, which is what some of us believe.”
“Or that there’s no such thing as death,” Luria said with a flicker in her eyes. “Just a change in state—from physical to spiritual, for lack of a better term. Think how extraordinary that would be.”
Zack’s mind was spinning. “Okay. Say I agree and go down a tunnel or whatever. How would you know that’s the afterlife and not some dream thing?”
“Because once you’re under, your brain cells can’t produce the necessary electrical activity. In short, you won’t be able to dream.”
“So what will you look for?”
“Anomalous neuroelectrical activity,” Stern said. “The key reason this hasn’t been done before is that the diagnostics didn’t exist. The MRI machine we used on you the other day is one of a kind. Its resolution power can distinguish individual brain cells.”
“We also have the software to make sophisticated mathematical analyses of any electrical activity,” Cates added.
“But I still don’t get how there can be any electrical activity if I’m anesthetized.”
“What the anesthetic does is to turn off intercellular activity, the long axon connections,” said Dr. Luria. “However, there may still be microelectrical activity in the channels between individual cells—what we refer to as analog communication, driven by cell-body-based properties. That’s what we’ll be looking for. And if there is any, we’ll need to analyze and explain that stimulation.”
“Such as what?”
“Such as human consciousness separating from the brain,” Luria said. “Mind transcending the body. To some that would be evidence that the afterlife is real.”
Zack was quiet for a moment as he tried to process what they were telling him. “And what would be proof of that?”
“The sixty-four-million-dollar question,” Luria said. “I suppose the ultimate test would be if someone comes back from an NDE with secrets only the dead possess.”
“However,” Stern added, “more skeptical people—me included—believe that the phenomenon is pure neurobiology—that is, the brain creating electrical-chemical reactions to impending death.”
“Religion versus science,” Zack said.
“Yes,” Dr. Stern said. “There’s evidence that the human brain is wired to encourage religious beliefs, some more than others. Skeptics claim it’s just biology. Others say God made us so wired in order to discover Him or Her.”
“Which is why your questionnaire asked if we were religious or into the occult.”
“Yes,” Luria said. “We don’t want subjects who are susceptible to paranormal phenomena because they’re prone to confabulating NDEs from something they read in a book.”
Or people who think they mind-merge while playing Texas hold ’em. And what about quoting Jesus in Jesus’s tongue while comatose?
“If I agreed,” Zack said, “how long would I be flatlined?”
“No more than three minutes.”
“Then you’ll revive me.”
“Yes, by turning off the infusion,” Sarah said. “Plus we’ll give you a small injection of norepinephrine, which instantly increases the heart rate and blood pressure.”
“What are the risks of something going wrong?”
“There are none. Zero.”
“How many others have you flatlined?”
“Many,” Luria said.
“And they all were revived,” Cates added.
“And all the same as they were before being flatlined?”
“Yes, no problems or side effects,” Luria answered.
Zack was silent for a moment as he processed it all. Then he asked, “Why me and why not my friend Damian?”
Dr. Luria’s birthmark darkened. “Well, as Morris said, some people are genetically predisposed to NDEs, which is why we did that helmet test on you. Your temporal lobe is highly sensitive to dissociative experiences. Damian’s wasn’t. In fact, most people’s aren’t.”
Dissociative experiences. Is that what happened at the blackjack table?
“May I ask how you’re funded?”
“Privately.”
But she did not elaborate. And clearly this was not research that was supported by university grants or the government.
“Any chance of me checking references—you know, talk to other test subjects?”
“We can’t do that because of confidentiality agreements,” Luria said. “But to reassure you, we have some videos of past NDE subjects in suspension and being revived.”
She turned the monitor around and clicked on a video, which lasted maybe half an hour. There were three separate subjects, two males and a female. Their faces were blurred, but Luria said they were in their twenties and thirties and all healthy. Each was lying on a gurney and speaking with Luria and others as technicians hooked up IV lines and wires to their head and chest. When they said they were ready, a technician administered something into their IVs, and almost instantly they fell into a deep sleep. In clear view of the camera were electric defibrillator paddles. The video ran for a few minutes while Luria and others watched the monitors. Then the subjects were awakened, each appearing groggy for a spell. One man seemed to relapse into suspension and was given a second injection of norepinephrine. Then, following a time jump, Dr. Luria was shown interviewing each—asking how they felt. All said normal. Then a short list of questions to assess their memories: Name the date, the current president, the state and its capital, and so forth. Luria turned off the sound while the interview continued.
“The rest involves their experiences, which we’re keeping confidential. We also don’t want to prejudice your own responses should you agree. Any questions?”
He didn’t seriously believe in the NDE stuff. His main concern was coming back from the chemical cocktail. “What’s the drug, by the way?”
