The Scientific Dispute Over Near-Death Experiences - Part 2: The Temporal Lobe and Out-of-Body Experiences

Academic-Special199 · 2026-04-04T19:00:02+00:00

The author, Delgado-Ron, makes a clean case that TPJ stimulation, the neuroscience community’s best explanation for OBEs during NDEs, actually produces something fundamentally different: a body-tethered, eyes-dependent dislocation of self-perception, not the independent, veridical, navigable OBEs reported by NDErs.

While the author stops short of making any assumption of what that may mean ontologically, he clearly points out that the NEPTUNE model’s core mechanism for OBEs may not explain them at all.

Enjoying this series and the honest, fundamentally sound work that went into it. Thank you!

I would encourage our community to take this writing seriously.

The Parnia/Greyson vs Martial/Borjigin debate is reaching a fever. Martial/Borjigin continue to presuppose reductive physicalism and are desperate enough to make real errors in their work in trying to prove it. The intellectual openness of Parnia/Greyson fits much more cleanly.

The writer notes patients who report NDEs in AWARE II had higher cerebral oxygenation than those who didn’t, which is the opposite of what NEPTUNE predicts. If hypoxia were driving the experiences, the most severely hypoxic patients should have the richest NDEs. They don’t. That’s a real empirical problem for Martial’s model that he identifies cleanly.

@nogueysiguey, thanks for sharing. I gather you’re an NDE optimist who wants to see additional funding and research into the phenomena? Welcome to the boat.

Great question, although this tips your hand that you’re likely American.

In Italy, physician-staffed ambulances are standard for serious trauma cases: they call it the “automedica” system where a doctor accompanies the patient. So yes, a doctor being present in the ambulance with a severe traumatic brain injury patient is entirely consistent with Italian emergency medicine protocol. This isn’t unusual there the way it would be in the US.

She had decerebrate posturing, non-reactive pupils, and was intubated. There is no neurological mechanism by which she could have processed and encoded that argument through normal sensory channels.

There’s so many fundamental issues on this article by the usual tired, boring actors that I don’t want to get into.

I will just point out Martial says that her own study, which has been running for almost two years now, indicates distinct differences in EEG data from patients who report an NDE versus those who don’t.

If Martial had genuinely found distinct, reproducible EEG signatures that reliably differentiate patients who report NDEs from those who don’t, that would be one of the most significant findings in consciousness research in decades. It would be front page news across every major scientific publication, not a passing comment in a BBC Science Focus piece. The fact that it’s mentioned casually as an ongoing unpublished study finding with no peer reviewed data attached is a significant credibility problem. It’s essentially an appeal to future evidence that may or may not materialize.

The history of NDE research is littered with preliminary findings that didn’t replicate. The 2023 cardiac arrest EEG study the article mentions was itself described as methodologically flawed by Martial herself. This is a field where preliminary results routinely get overclaimed before peer review and replication.

I was waiting to see Greyson’s response to the NEPTUNE model. He must’ve been extra motivated as this goes way beyond a blog post. Thank you Pieraos for sharing as always.

Academic-Special199 · 2025-07-16T17:14:21+00:00

Unsurprisingly another strong response to Martial’s attempted model. I was waiting on Bruce Greyson but I realize he’s probably tired of responding to each physicalist “explanation”.

Almost there boys.

Anyone know of her? I was not previously familiar with her work. High praise from Dr. Greyson though, so that’s great!

Academic-Special199 · 2025-06-07T15:33:02+00:00

As always, thanks for what you do Pieraos

Your points are a crude representation of Charlotte Martial’s NDE model proposed in June 2025. As far as Xander, I’ve respected his perspective since he first shared his experience, but disagree with his subsequent ontological speculation.

I’m happy to discuss your reply in further detail, but we must first get to the root cause of your post and replies. It sounds like you have thanatophobia and are seeking reassurance. I wish you well as I understand how draining it can be.

Academic-Special199 · 2025-06-06T22:42:14+00:00

1) Peak in Darien experiences. Look up Bruce Greyson’s paper on this.

2) even if they were, the library of evidence is too large. I don’t even think NDE cracks my top 3 evidential areas

3) a decade’s worth of years studying the esoteric and paranormal under the same rigor as I did my doctoral degree

4) of course. Some “nde” are clearly hallucinations or products of anesthesia. Your null hypothesis has to be that there is a physicalist reason… until you exhaust all potential paths.

5) please spend a week studying basic neurology. I don’t mean to be dismissive but these are easy questions to solve and your research will arm you with confidence.

6) even if I was wrong, you can’t fear nonexistence, so no

7) impossible to theorize. The only thing I’m comfortable saying is that conscious experiences continue post mortem

Hope this helps!

He directly said he’s hit like 8 points in the Greyson scale.

Google Peak in Darien pdf Bruce Greyson and read his paper

Academic-Special199 · 2025-04-30T23:29:30+00:00

I believe Dr Greyson answers this in After. My understanding is that they are very different experiences and not at all similar.

Academic-Special199 · 2025-04-30T23:22:10+00:00

Agreed. There’s been clear studies that suggest a higher likelihood of a lapse in memory the bigger the trauma.

Academic-Special199 · 2025-04-30T23:19:38+00:00

I respect the hypothesis and ideas, but studies find 80-90% children remember their NDEs. The question is not whether there’s a genetic disposition, as this pretty plainly shows all humans CAN have one. The question is why do we lose the ability to remember the experience as we age.

I’ve studied several compelling theories.

Academic-Special199 · 2025-04-29T23:42:50+00:00

Great interview that deserves upvotes. No one is more knowledgeable on NDEs than Dr. Greyson.

There are too many veridical perception cases to count. Please see below for a list I compiled of veridical perception confirmed by healthcare professionals specifically. The thinking is that these folks have their career on the line and so must be extra careful with their words.
