need to call ghost busters . your dead granny ain't gonna call you up ! carcass rots whether human or insect . chemicals alter your perception and that is all .
I've thought and read about this, oh, just a tiny little bit.
First may I ask: What psychedelics have you done and in what amounts? Please don't fib.
Anyway, as a little starting exercise, please elucidate exactly what "red" is (intrinsically or as compared to say "blue") to someone who has been blind from birth. Not a frequency number, but THE
MEANING OF THE TERM "RED" WHEN YOU SEE THAT COLOR. You may use as many scientific words, diagrams, equations, and computers as you like. Go ahead, Mr. Smartypants. Well? WELL???
So...if the contents of our subjective impressions and feelings and perceptions are 100% generated inside of our brains, explain exactly what/why it is that it should FEEL LIKE anything to be a set of firing neurons?
And WHAT, exactly is it that IS FEELING WHAT IT FEELS LIKE TO BE A SET OF FIRING NEURONS???
In what ontological dimension are our subjective conscious perceptions and inner thoughts and feelings occurring, exactly?
How, exactly, does a mere set of molecules arranged into neurons, just because they are carrying electrical charges etc., suddenly acquire an internal subjective sensation that they "ARE" ANYTHING? i.e., how, exactly does dead matter magically generate the internal impression of consciousness?
There is a long history going back centuries in pure philosophy in which the idea of our awareness just being some sort of physical process running on a mechanistic bio-computer has been logically proven to be quite incomplete and insufficient.
ALL physicalist explanations are just arm waving and offer ZERO accounting for this aspect of the phenomenon, just brushing it off to the side as if it does not matter. Saying awareness "is just an epi-phenomenon" or something like that is a laughable way of saying "I have absolutely no idea" using a great big word and hoping the questioner would just go away.
Philosophers, physicists, and biologists are still arguing extensively about this.
It's known as "The Hard Problem", also the issue of "Qualia". Look those terms up on Wikipedia and do some reading and your certainty may waver.
Here are some starting points, Mr. Certainty:
Start here with the concept of "Qualia" and branch out from there to explore the philosophical history & current elaborations:

Stuart Hameroff MD and Roger Penrose PHD. Their recent theory about the nature and mechanisms of subjective conscioussness/awareness is nicely sumarized by Hameroff:
"It is argued here that the physicalist premise alone is unable to solve completely the difficult issues of consciousness (e.g. experience, binding, pre-conscious conscious transition, non-computability and free will) and that to do so will require supplemental panpsychist/pan-experiential philosophy expressed in modern physics. In one such scheme proto-conscious experience is a basic property of physical reality accessible to a quantum process associated with brain activity. The proposed process is Roger Penrose's objective reduction (OR), a self-organizing "collapse" of the quantum wave function related to instability at the most basic level of spacetime geometry. In the Penrose-Hameroff model of "orchestrated objective reduction" ("Orch OR"), OR quantum computation occurs in cytoskeletal microtubules within the brain's neurons and links cognition with proto-conscious experience and Platonic values embedded in spacetime geometry. The basic idea is that consciousness involves brain activities coupled to self-organizing ripples in fundamental reality."
Above is from the following utterly fascinating and very well developed article:
http://www.quantumconsciousness.org/penrose-hameroff/fundamentality.html
This is the proposed mechanism whereby quantum physics is directly linked with the subjective experience of consciousness... as you may know quantum physics is already intimately associated with consciousness... uncertainty principle, collapse of wave function, Schrodingers cat, etc. This is not new age mumbo jumbo. Quantum physics is oh so very real... the very computer you are on now (the mechanism whereby transistors functon on an atomic level) would not be possible without it.
And don't say "quantum processes only occur at quantum sizes and cannot possibly affect things like living systems. WRONG:
For those still skeptical that biological systems can possibly have anything to do with quantum-type events & processes... not so fast! There is mounting evidence that macroscopic bio-organisms capture and USE even the fleeting flickers of the quantum world in the struggle for survival... the process of evolution via DNA mutations is, apparently, able to capture and utilize ANY physical qualities, even quantum ones:
http://www.quantumconsciousness.org/qbupdate.htm
Support for the above theories is being collected here, for example:
<Tunneling and green tea J Am Chem Soc 129 (18) pp 5846 - 5854 " Tunneling is a ubiquitous phenomenon in nature [...] We had a problem understanding how polyphenols work at such low concentrations. This paper gives theoretical credence to a large amount of experimental evidence of polyphenols as in vitro and in vivo antioxidants. ">
I KNEW THERE WAS A REASON I LIKED THE STUFF.... And I guess this explains how EGCG ended up being such a powerful, useful medication!
<Evidence for wavelike energy transfer through quantum coherence in photosynthetic systems Berkeley Lab In Nature 446, 782-786, Fleming et al. report on coherent electron transfer in photosynthetic complexes. " We have obtained the first direct evidence that remarkably long-lived wavelike electronic quantum coherence plays an important part in energy transfer processes during photosynthesis. This wavelike characteristic can explain the extreme efficiency of the energy transfer, because it enables the system to simultaneously sample all the potential energy pathways and choose the most efficient one. " Covered also in Scientific American, Wired, PhysicsWeb,rose.blog.>
So, to implement that most magical of natural processes, photosynthesis, our greatest planetary magicians, THE PLANTS! figured out how to use manipulate matter's quantum properties!
And most spectacularly, scientific evidence that DNA managed to cook up a a biological structure/process that allows ANIMAL BRAINS to harness quantum properties to perform a function that increases the survival of the animal, and thus, of course, of the DNA... amazing!!!

Quantum Zeno Effect Underpinning the Radical-Ion-Pair Mechanism of Avian Magnetoreception

Abstract: The intricate biochemical processes underlying avian magnetoreception, the sensory ability of migratory birds to navigate using earths magnetic field, have been narrowed down to spin-dependent recombination of radical-ion pairs to be found in avian species retinal proteins. The avian magnetic field detection is governed by the interplay between magnetic interactions of the radicals unpaired electrons and the radicals recombination dynamics. Critical to this mechanism is the long lifetime of the radical-pair spin coherence, so that the weak geomagnetic field will have a chance to signal its presence. It is here shown that a fundamental quantum phenomenon, the quantum Zeno effect, is at the basis of the radical-ion-pair magnetoreception mechanism. The quantum Zeno effect naturally leads to long spin coherence lifetimes, without any constraints on the systems physical parameters, ensuring the robustness of this sensory mechanism. Basic experimental observations regarding avian magnetic sensitivity are seamlessly derived. These include the magnetic sensitivity functional window and the heading error of oriented bird ensembles, which so far evaded theoretical justification. The findings presented here could be highly relevant to similar mechanisms at work in photosynthetic reactions. They also trigger fundamental questions about the evolutionary mechanisms that enabled avian species to make optimal use of quantum measurement laws.
