Hi,

This is interesting because not too many years ago if you tried to categorize
this as electronics related it would not have been possible, but today there
are brain implants that can read some of the fundamental brain signals and
operate machinery like prosthetic hands with fingers. Unfortunately this
requires surgery, so it's more or less for those who really need it right now.
A chip is installed in the brain in the region that is responsible for that kind
of movement/control and it is wired to a computer. The computer algorithm
interprets the brain signals and decodes into the correct movements via the
machinery. In this way when a person 'thinks' about opening and closing
the hand it really does open and close, even though the person has no
real hand anymore.
Would this work with a person that was born with a defect in that area of the
brain? Probably not, but at least it works with people that once had hands
and so that one area of the brain was at one time working ok.

Yes, and if you are actually hearing sounds it seems to reason that the parts of the brain responsible for processing speech would light up in an MRI or something.

If we did our thinking in words we would not search for the right words to express our thoughts.

I suspect that language and thinking are not totally independent. We may not think in sentences but our vocabulary influences the process.

Please do not ignore my question thinking it to be non-technical...
I don't think that you can ignore the spiritual side of it, because you are in fact dealing with spiritual questioning.

I believe that we are a spirit, we have a soul, and we live in a body....If you only try to get answers from the body (brain, electrical impulses, etc...) and ignore the soul and spirit you will never get the answer to your question. Intuition, communion with God, and conscientiousness are all related to the spirit. The soul is emotion, volition (will) , and self. The body is matter so it only deals with the material aspect.

So the spirit is God conscience, The soul is Self conscience, and the body is world conscience.

Think about it...if all we had to think with or reason with was a brain. How could we have an inward voice. If the brain was all that was thinking...how can we ignore every whim of thought. If I choose to do something that's wrong for instance...doesn't the voice of conscience come out against my decision to do it. Only after I choose to ignore it's plea through resisting and reasoning does it take a back seat.

So the point being, the will (soul) is the deciding factor, becuase the will chooses what voice it will listen to. Right, Wrong, or Indifferent.

Just my 2 cents worth!

I would rather be left with an honest question than take a lie for an answer.

Actually your correct I recently watched a study about that very thing.

They used someone's mind first playing Beethoven the regions of the brain stimulated mostly the frontal lobes part of it was in the parietal lobe but still mostly in the frontal lobes.

When they were asked to play the image of the music back in their mind they were stimulated in the same regions similarly.

So, by mapping the same regions may result as the mind then would create the words. I myself pass beyond it like someone else said here.

I don't here the voice while reading. It's like I just know the meaning and do not pay any attention to the actual sounding of it phonetically in my mind.

I am a word thinker myself. Every thought I can come up with is sort of like having a really brilliant person or several people in my mind telling me how to make something or understand something!

I am a clueless dummy but the voices in my head are absolute geniuses!
(And one rather fair comedian.)

Go figure.

The inner ear is where our hearing converts mechanical hearing to bio electrical signals that the brain processes. I am certain it is possible to share these signals between two people. How? I have no idea, but interesting question none the less.

Default Inner Voices

I don't actually hear voices in my head. But, when I was a child, I occasionally would. Like I would hear my mother call me in...and then find that she hadn't.

But, I do have a pretty active inner dialog and often teach myself things. That is, I go through the same process of explaining them to myself (including all the arguments, back and forth) as if explaining them to another person.

I have extremely vivid dreams and am often amazed at the level of detail. In fact, I sometimes will sort of stop, during the dream, and try to analyze what I'm seeing in the hopes of remembering it better when I wake up so, I know that, at least sometimes, I have a sense that I am dreaming. Unfortunately, most dreams are lost on awakening and, even the dreams that are remembered lose virtually all of those fine details.

When I do design work and talk to myself, it's a lot like my inner monologue but, of course, vocalized. There's a really terrible old movie, Frankenhooker where this guy accidentally kills his girlfriend with a lawnmower and attempts to put her back together again. There's a scene where he's figuring out the details. Of course, it's technically inaccurate but, the process would be familiar to most technicians and engineers as he talks himself through the circuitry.

I've been mulling a movie script in my head for the past few months where a gang of Middle East terrorists have acquired a nuclear bomb they are going to detonate in a US city. The FBI captures one of the planners but, due to some sub-plots involving a "politically correct" US President, who wont allow torture, the terrorist wont divulge his knowledge and the bomb plot continues. Anyway, some rogue agents decide to get the info by other means. They do brain scans on the terrorist to isolate activity for certain questions and then actually, surgically remove and transplant those brain bits to another person to get the data. Of course, one of the brain bit recipients is a little girl with terminal brain cancer who agrees to help (more sub-plots of the struggle of the parents, etc.). Anyway, you get the idea. I have the basic story line blocked out but, I'm looking for colaborators for this script (people who have technical knowledge on tactical nuclear weapons and remote detonators, MRI techniques, brain surgery, political and governmental machinery, Middle Eastern customs and personalities, military and industrial air, sea and land transport and border customs, etc. etc.). Oh, yeah...and people with the interest, writing skills and knowledge of motion picture script writing (using the, Final Draft scriptwriting program).

I feel some pressure to get this script written before the science fiction becomes science fact!

I couldn't get your link to work. Here's an interesting link: Broca's area - Wikipedia, the free encyclopedia. Some people have mentioned visualizing while thinking. Here's another interesting link: Visual cortex - Wikipedia, the free encyclopedia. Of course, this doesn't isolate anything. I've wondered how diverse and unique the origin of worded thoughts - having a common dictionary meaning, may be in people. What really is their functionality? Are the ones' that allow people to socially survive nothing more than the result of a trend that results in sophisticated coincidences? What functionality and meaning can they have if not shared with people? What causes the development of new languages?

Cochlear implants are commonly used as therapies for some kinds of deafness. When the nerves to the brain are intact but the inner ear isn't working, they can stimulate the nerve ends directly.

It has to be a very short step to a cochlear implant that parallel processes audio signals alongside a healthy inner ear. One that can be connected to a radio receiver to directly and remotely send audio to a person. It's a bit surprizing that something like that hasn't already shown up in a James Bond movie.

Do you really want someone to be able to talk to you 24 hours a day from inside your head?
And what happens when the FCC changes the frequency it works on into something like a public access communications frequency? 24 hours of nuts with transmitters running through your head!

No thanks.
The voices I have now at least get along and will shut up when I want them too!

I suppose that this post could be at least three: the nature of this type of voice, the nature of thought, methods of transferring signals, and ways producing signals.
