Mohseni and Nudo's research on traumatic brain injuries was inspired by the number of soldiers who suffer from this every day  (Source: Military Times)
A microchip on a circuit board could bring axons together restoring physical and emotional abilities

Researchers are working to recover normal movement and behavior within patients who have suffered brain damage by creating microelectronic circuitry that will promote the reconnection of neurons and growth of axons.

This type of work was inspired by the brain injuries and trauma the troops in Iraq and Afghanistan face. Pedram Mohseni, a professor of electrical engineering and computer science at Case Western Reserve University, along with Randolph J. Nudo, professor of molecular and integrative physiology at Kansas University Medical Center, are the top researchers on this project who recognize that head trauma/injury is common in injured soldiers, despite their use of armor and helmets.

Brain damage comes with side effects that can drastically alter a person's normal reality, such as loss of mobility, balance, coordination and problem-solving skills. Emotional side effects include depression, anxiety, social inappropriateness, emotional outbursts, mood swings and aggression.

But now, further research of these injuries indicates that a healthy brain, as it develops, creates and maintains communication pathways that allow neurons to "repeatedly fire together." So Mohseni and Nudo's new research revolves around the repeated communications between neurons who are distant only weeks after injury, which could lead to the reconnection of distant axons as well. 

Researchers note that the month following an injury is a crucial time period in their research because the brain is redeveloping at this point. This allows them to perform extensive rewiring where the brain cannot do so itself.

"The month following injury is a window of opportunity," said Mohseni. "We believe we can do this with an injured brain, which is very malleable."

Both researchers are able to do this by bringing their separate projects and expertise together. Mohseni has been developing a multichannel microelectronic device called a brain-machine-brain interface, which is capable of bypassing gaps left after injury. This device works through a microchip, which is smaller than a quarter, on a circuit board where the microchip amplifies neural action potentials, which are signals created by one part of the brain. An algorithm is then used to separate signals, which indicate brain spike activity from noise. 

When brain spike activity is found, the microchip delivers a "current pulse" to activate neurons in another part of the brain, thus reconnecting both regions of the brain. 

Nudo contributed his expertise on brain activity, after studying and mapping brain activity in rats, then testing the new device and the neuroanatomical rewiring theory on a traumatic brain injury model. 

The brain-machine-brain interface is a miniature device that connects to microelectrodes implanted in two regions of the brain, and stays outside of the body. 

In the future, Mohseni and Nudo hope to test their ability to rewire the brain further on rat models. If this process turns out well, they would like to move on to testing this procedure on non-human primates. If the primates are able to recover from brain injuries after extensive rewiring, Mohseni and Nudo see human patients using this in approximately 10 years.

And so the research is born!

This sounds like the very early beginnings of knowledge implants!

Very. Early.

But one day I could see this evolving to interact more with the brain, ultimately arriving to a point where the human mind can actually communicate with an implanted chip.

It sounds somewhat ludicrous considering current technology, but if it ever meets reality, that technology will be the next big industrial boom in our world.

I think that the silicon technology is there already, but it is the connection and signal paths in the brain that will contribute most of the roadblocks in the future. Also think of the software...... You would really need to know what someone was thinking in order to interpret it, privacy rights anyone?

I love how everyone has consummate knowledge of anything to do with this type of injury. I find this all very interesting largely because I have been the victim of immense trauma in my right frontal lobe. This happened when I fell 39 feet off of a highway bridge (Shallowford road 85 N Atlanta GA), and then was pronounced doa. I was in a coma for roughly a month and a half following this incident.

This is very interesting work as well as a very beneficial path to follow. I love the Skynet/Matrix comments, but as far as I know having a wireless connection would be optional and require more hardware to be added. As far as it goes a soul is a personal belief.

Yes; I may believe in it, but that is up to you personally. I would say a cognitive soul would be contained in a person's brain. However; to a much greater amount in the being of an individual. While this is all a psychological question as well as a philosophical discussion, I personally believe in it as a constant (IE: it is part of what makes you, you).

Either way these type of injuries are had daily by many many people. So this type of work, and research, is over all very beneficial medically as well as to the human race in general.

Whether you believe this or are an atheist etc, etc does not matter in the least. As I am sure the doctors would tell you if you asked. You could not be an atheist or a christian, Muslim, Buddhist or anything if your brain did not function fully.

Within my soul there are some brain ideas and sometimes images of some brains. Thats all I can tell for sure. The 'brain' is something within the soul. Too wich of these brain ideas or representation do you want me to fit in? What is the hole you want to dig me in? Sorry everyone but I am much more then any of your ideas or perception you want to reduce me in. Defective brains or obsolete computers needs be replaced. Good luck when you get treated by those who thinks like you.

Oups, sorry atlmann10, this was not intended to be a reply of yours. not at all.

Seems a larger market would be to give this to people that never had full brain functionality to begin with, which by my rough estimations is about 70% of the population. Could this finally be a cure for stupidity?

1) What does this have to do with the article at all?

2) Those who believe in a soul do not believe it is contained solely in the brain.

Do you want to say converse about the Jung approach or are you just going to make the most general statement possible to get the words GARYJOHNSON somewhere someone will read it.

That makes even less sense than your other statement."The Jung approach" doesn't relate to the article, this comment thread, your post, or my post in any way. So I would have to say that, "No, I don't want to converse about the Jung approach."

Really guys, does anybody think that this has to do with the "Soul"?

Now conciseness is something that might be connected here and despite what atheists and religious types think, there is ongoing research on where our conciseness comes from. As of now, it continues to be a mystery that can't all be explained by the "Brain As A Organic Computer" explanation.

Actually the brain is a very slow and inefficient analog computer.

I am going to argue with you, not because I actually disagree with you.

You say it is slow, because of visual FPS 30 distinct 60 partial images?

We know that brain actualization is easily calculated?

The brain is able to represent everything in binary and some sort cubit state?

Or, even the deprecation of resistive memory?

can you elaborate, again don't disagree just want reason.

I believe he is saying it is slow, because compared to a computer, it is slow. The average action potential takes one millisecond, which is quite slow relative to a computer. Motor neurons are even slower.

First of all the Brain isn't a computer, it's an organ.

And if you wish to compare it to a computer it is in fact a highly complex massively parallel multi-tasker that can put any computer to shame. Consider the math that goes into catching a ball and then get me a computer that can do that along with processing all the other information the brain receives about its environment.

And I haven't even begun to mention art or emotion....

I did not say it was not the most incredible accomplishment of evolution on earth just that it was slow in its signal propagation capability and inefficient in that it has a lot of evolutionary baggage in it. Nature is inherently lazy, and thus evolution is not exactly an optimization process.

Not a single person posting here realize that all their views, ideas, opinions, are happening within what we call 'soul'. And yes this little article, like this computer idea, and my response to it is a 'phenomene' of conscience. It is, because your 'soul' is a-conscience-of-it. The subject folks is never seen but is what sees, the reason is not tough-of but is what thinks. Do not reduce being to an object there. Do not reduce human to a computer. Beware of scientific dictatorship! Beware of yourself.
