Some people can say "yes" to the doctor, not for a complete artificial
brain, but for a part of the brain.
Taking a drug, or a psycho-active substance is already an act of that
type. Some molecules build by some plants (in general to attract or
manipulate insects by acting on their brains or nervous system) can
already be considered as "artificial subpart" of your brain (at the
molecular level). The use of more and more specific agonist molecules
for the brain molecules, is a way to learn about the brain, and how
good can some new molecules can be to do some job in the brain. People
will not necessarily ever say really "yes" to a doctor, but they will
be propose evolving artificial part of the brain.
Well, what I say, is that the self-brain-study, through entheogen, may
accelerate the development of artificial brain parts.

Exactly. We may never understand the whole human brain, but we can
find those correlation by self-testing.

This is weird. What is a psychedelic properties? It is vague term.
I think that studies of that kind have been made on some meditation

Yes. It is very informative on the consciousness phenomenon. It is fun
too. I have a read a lot also of all the possible diaries of dreams,
and I have written and studied my own dreams. I am no more, because it
asks for work, a good lucid dreamer, but I have practice and develop
technics at times, and the tools (mainly coffee!) to practice lucidity
the night. Nowadays I use calea zacatechichi or salvia, which have
some interesting impact on dreams (also on the "non REM dreams",
hypnagogic images, etc.
"Conscience et mécanisme" contains a chapter on dreams, I tend to
follow Hobson, and Dement, LaBerge, and Jouvet. In the REM dream, we
are awake, hallucinated and paralysed. The cerebral stem plays a key

Not only it is relevant, but it is at the cross of many levels of
description of the data which we have to take into account if we want
to progress on the everything riddle.
The relation between a Brain and a Reality is akin to
the relation between a Theory/Machine and a Model, in logic, and to
the relation between an equation and its solution, in algebra.
The common point is a "Galois connection" which entails something
like, roughly speaking, that to a self-perburtation of the "brain, or
the theory/machine, or equation" will correspond an exploration of
nearer set of possible "subjective realities" (for the brain), of
models for theories, or solutions for the equations.
Reversible self-perturbations of the brain, may help to progress in
the consciousness, realities, number relation, but has been used by
the brain itself all along its evolution. Some technic in artificial
Intelligence can be described in similar terms. Nature, by which I
mean the natural numbers (grin) allows feedback between high and low
