My conclusion from that quote is that conciousness is independent of brain, is not produced by the brain, it merely activates the brain. Conciousness is independent due to the fact the NDEer has knowledge of things while his body/brain is suspended.
The paper says hallucinations dont account for the veridical knowledge.
Your thoughts?
I think that's a pretty good conclusion to what he wrote.
So, I'll try critique it and say what my conclusion is. I'll cut it into two sections and then a further two sections. First I'll summarise than I'll critique it
"Hallucinatory-type explanations simply do not fit the growing
body of data or else appear hopelessly ad hoc. For example, they do
not account for the patient's knowledge of events in the operating
room. In addition, characteristics which define hallucinations are
missing in NDEs."
Summary
He seems to mean that scientists haven't studied this particular phenomena, because he talks about data. He gives an example where either we haven't studied the patients knowledge of events in the operating room or people that experience NDE don't have them. I'm going to say that it's the prior(they aren't studied), because, he mentions later on in the paper, that people have had outer body experience in NDE as displayed by this quote, "Patients who reportedly leave their bodies in operating rooms often describe with great precision the goings-on in the room during their near-death experience." So, he's saying people do have them but they're not studied. Lastly, in this section, he implies that they don't seem to fit the hallucination definition. Basically, what is a hallucination so it may not be that but rather something else.
Critique
1: there have actually been studies since this has been written that take into consideration hallucination and knowledge of operating rooms.
2: This paper is nearly 40 years(38-39) old, so they may have not been studied prior to this paper it was probably difficult to get a hold of them, because of no internet.
3: The definition critique, in the last section, seems odd to me because he doesn't seem go into detail or supply references.
4: no references are mentioned here - science or otherwise.
So now let's look at the next section.
"Moreover, at least one cardiologist claims to have
correlated NDEs with flat EEGs, a claim which, if born out, would
appear to rule out the possibility of hallucinations."
Summary
I have actually practised with EEG and know something about them. They measure electrical signals from the brain by placing electrodes along the scalp. They measure surface activity and brain waves and have been divided into various sub groups- alpha, beta, etc. Now, flat EEG would probably mean a dead brain.
Critique
1: He has one reference that I can't even find, so it's difficult to examine.
2: Assuming the brain is actually fully dead, another possible explanation is that it's similar to a dream and catches up when they wake. For instance, sometimes dreaming for 1 minute can make someone have a dream that seems incredibly long. This is anecdotal though.
3: Let's assume that the patient managed to attain memories while their brain is fully dead, then that would mean there's something soul-like or energy-like, etc, that accumulated these memories( this particular critique is pima facie pro some kind of soul or energy.)
4: So, we have to assume the brain is dead based on this EEG correlation study and we have to assume that memories were attained during this dead state.
Conclusion he comes to:
Something other than the brain is creating memories or could be.
