Knowing the science-junkies around here, I was surprised that this article had not been posted.

A conscious ping.

Actually, I think it was posted here a couple weeks ago.

AHHH... So tinfoil hats don't prevent reception, they prevent transmission.

Isn't chemistry an 'electron kinda thing'?
Kinda like everything you can see, hear, taste, feel, or smell?

The answer is that our skin, skull and cerebrospinal fluid shield us from external electric fields.
And a thin layer of metallic tin wrapped around the cranium provides an additional protective barrier against not only electromagnetic radiation but mind control beams, laser death rays, and coded transmissions from alien satellites.

If this theory - that the mind is just an electromagnetic field - is ocrrect, then anyone who passes through an electromagnetic field would have their thoughts ... POLARIZED!

Thanks for posting this! If it was posted before, I missed it.

What is an electric field? Is that the same
as a magnetic field? I thought it took something
like lead and a lot of it to shield something from
an electromagnetic field. And can anything stop
a magnetic field? I don't unnerstan'.

If consciousness were nothing but the vector sum of the electromagnetic fields generated by the neurons, why would an Xray (penetrating electromagnetic radiation) not cause some distortion of the psyche? The cat scan (an entire series of Xrays) of my head early this year might have been the cause for me to change my mind about unqualified support of the President's domestic policies. And if I ever need to have an MRI (exposure to extremely high static and oscillating magnetic fields), I'll have to find out if my insurance pays for treatment of raving, ranting liberalism, just in case!
A couple of things ..... if this is the case then why are people's minds not scrambled when placed into extreme electromagnetic fields ? Electrical shock of any kind would have devastating consequences for a mind.
It does not and people's minds are not scrambled by extreme magnetic fields.
Junk science is this, or GIGO.

At least it can be said that electromagnetism inherently performs an algorithm in propagating.
I believe that the brain evolved while excluding significant external EM fields. By paying attention to the timing of signal components picked up by different antennas, an array of antennas can focus on a selected area to the exclusion of others, and a similar process may be used by the current carriers of the brain as they propagate and receive internally-generated EM energy.
I think that consciousness is dependent on the degree of effective complexity in the neural wiring, and I think that free will is what consciousness has during free time, when no ideal or pressing mental pursuit is apparent.
Language, creativity, emotions, spirituality, logical deduction, mental arithmetic, our sense of fairness, truth, ethics, are all inconceivable without consciousness.
That's not really true. Either that, or Professor McFadden doesn't have quite the right understanding of "consciousness". Computers can be programmed with surprising capabilities that, more and more, can pass for all these things that he describes. But it would still be a stretch to call them "conscious". Consciousness is that which can't be described objectively - for example, there's no way to describe sensations of color, sound, pain, emotion, to any being that hasn't experienced any of these things. These are the things that constitute consciousness.

I thought this was posted a few weeks ago. Perhaps it was a sub-reference, but there was some discussion. It's a weak hypothesis, that is to say, obvious, adding nothing, and explaining less. Parapsychologists like this kind of thing.
What's the frequency, Kenneth?

My further take on things:
Consciousness, as most people know it, goes beyond whatever is required of the brain to integrate all the senses. Consciousness adds to that capacity a modeling mechanism for interpeting the sensory input in terms of a hierarchy of efficient, abstract generalized models. Beyond that, consciousness has a sense of place in the hierarchy. Human consciousness is capable of evaluating large numbers of potential scenarios, including potential self-placement scenarios. Because of this, consciousness is capable of considering: the act of considering: the act of considering: ... , et cetera, for any concept it can simply consider, if needed. All of this will be emulated by computers eventually, and clear distinctions between conscious and non-conscious will disappear.
