Interesting topic!
I'm really enjoying getting into the philosophical aspects of consciousness through this thread, since, unsurprisingly, I'm more versed in the biological and biochemical aspects of the brain. Serotonin, norepinephrine, acetylcholine and others mediate and may even be thought to
cause certain cortical processes (e.g. false memories, etc...), and serve as a basis for consciousness. Mess with any of them through chemical or physical means, and consciousness becomes, shall we say,
altered.
I'd have to do a little reading in my buried textbooks about general anesthesia, but I'd be particularly interested in how it seems to "remove" consciousness from a philosophical versus biological standpoint. And do the various prescription antidepressant or psychotropic medications (to say nothing of the myriad
illicit substances out there
) actually serve to create an artificial consciousness by way of altering the neurochemicals?
Just thought I'd put a different spin on the subject.
Have a good one.
p.s. It's a shame about 'ol Darrell, innit? An all-around likeable guy and
damn fine guitarist.
