deep brain activity during NDE's?

Just bringing this up for discussion   . I haven't really seen this type of argument anywhere on the site , so here it is:

"I'm already there. I've been there for a long time. Long enough to review it all dozens of times, and I always arrive at the same conclusion. Although we don't know everything, we know enough to be sure that assumptions like those you allude to cannot reflect the actual state of affairs. There is no verifiable evidence that concepts like "higher selves" that facilitate movement in "extended consciousness realms" are anything more than imaginary places our minds dream-up. Anyone who has vivid dreams can tell you that the whole experience is completely lifelike — mine certainly are.

The brain is just that powerful. Even in cases where there seems to be some correlation between a dream state or OOBE experience, and objective reality, all that has happened is the acquisition of matching data, and that acquisition can usually be explained by a combination of sensory data, memory, and automatic visualization. It doesn't mean the person actually went anyplace and saw anything objectively real."

i wanted to ask why he would think that way , and based on what sources has he reached that conclusion , but this comment is around 2 years old , (i found it on skeptiko) and i don't think the author is still using the website since his last login was 2 years ago approximately , so i decided to bring it here and maybe spark a discussion.

and that acquisition can usually be explained by a combination of sensory data, memory, and automatic visualization. It doesn't mean the person actually went anyplace and saw anything objectively real.

also , i would like to know if the brain still gathers sensory data during cardiac arrest/anesthesia , i'm not knowledgeable at all on this type of situations so a little bit of help would be appreciated , have a great day!

It's a tricky thing when looking into stuff like this. If anyone starts bringing up higher selves, extended consciousness realms, that tends be where I zone out because really there's no way we know so there's no point adding undue speculation into stuff. There's also a lot of NDEs, OBEs ect that can have conventional explanations and I think they do, it's a lot of things that are grouped under one phenomena and sometimes more conventional things can leak in. 

The brain is an incredible powerful thing. It can piece together and create entire stories out of snippets of information, information that we don't even need to consciously recall obtaining. That's why NDEs are interesting and I assume it's what's being talked about in your quote, because its situations where the brain can't take in or make sense of ANY information, yet people can still have accurate recolection of events. It's very easy to just slap that whole speele down and if you look at NDEs from a very broad general sense it's an easy explanation to give yourself, but when you get down to the nitty gritty of things and look at the actual cases and examples it doesn't at all apply to all of them. 

The brain does still gather sensory data while under light anaesthesia, though under heavier ones for more serious surgeries the brain generally cannot gather any information at all because the methods for it doing so are completely repressed. Same for cardiac arrest, during its very very early stages the brain is still functioning but once it kicks off the parts of the brain used for creating memories simply don't work anymore.

Hello! Thank you for the reply! & yes , i was mostly talking about NDE's but it was also a curiosity of mine  . Have a great day!

Agree with much of your post as a sensible skeptical position to take... regarding very deep anesthesia there is interesting new evidence confirming a couple of earlier studies, that the V1 visual, and auditory areas of the brain are disconnected from the rest of the brain during burst suppression. I wrote about this in a post on here a couple of years ago (linked below).

Sirmpilatze's findings oppose the view that burst suppression is a global cortical event. Instead they find that the visual areas and some auditory areas of the cortex in humans are completely disconnected from bursting... they do something completely different... I found that very interesting...
