okay, I've noted snippets of the article you linked as external text, then posted the anesthesiologist's response below them.
Staying with the darker side of life, It’s not a subject often dwelt upon but one of life’s truest mysteries is that we have no idea why
anaesthetics work,
Don’t know exact mechanism but have hypothesis
Propophol works on the Gaba receptors in the brain. Gaba are the inhibitory receptors, it prevents transmission of other neurotransmitters:
memory/cognition/pain.
The volatile, or the inhaled ones, such as halothane/isoflourine/cevoflourine/desflourine (no idea how to spell those), are used to keep you asleep.
These work on different receptors in the brain.
writing throughout recorded history show how attempts to produce states of general anesthesia were sought by the ancient Sumerians, Babylonians,
Assyrians, Egyptians, Greek, Romans, Indians, and Chinese. For anybody who has experienced it, after you accept the inoculation in the arm or hand and
are asked to count down from five you never reach the final count because – Bang ! – you’ve sank into the vast blackness, a genuine occult
experience, and return in the same timeless moment with no dreams and no recollection of the voyage.
The shot is propophol, which occupies the Gaba receptors and basically shuts the brain down. Once the propophol starts to work, then the intubation
is performed so the gas can be administered. This in addition to paralytic meds that are administered to keep the patient immobile. The paralytics
have nothing to do with conciousness.
It is thought that how general anaesthetics work has something to do with the cell membrane of a nerve cell and yet realistically it is a subject
that nobody can comment on.
Cell membranes are where the Gaba receptors are located. By using anesthetics, which bind those membrane receptors, the result is the prevention of
transmission of normal impulses.
That there is no dreaming is significant as in the animist paradigm of the ancient beliefs of the Aborigine…, If we do dream whilst under
anaesthetic we certainly have no recall… ….., we know that anaesthetic ‘freezes’ the nerves around specific parts of the body.
There is no dreaming because the EEG, which is used to monitor brain function while under anesthesia, records no brain activity that is indicative of
stage 3 or 4 REM, or dream-wave patterns. There is brain activity but no “dream state” activity. It shows only state 1 and 2 REM where no dream
activity is normally said to take place and the body is in a state of self-induced paralysis.
My comments:
Personally, I think there is capability to dream in REM 1 & 2, because I've done it and remembered what I was dreaming about. I think this is also
where lucid dreaming takes place, which is something I also do myself.
The anesthesiologist said he has never experienced someone reporting dream activity or memory of what occured while under anesthesia.....except for
one individual who's propophol wore off before the gas was turned on.
