There is no sleeping on this thread that's for sure!
I am aware of the Phantom Limb issue, which is why i stated a
"baby" as a baby's brain is in rapid development and that is a time when we develop most of our neural wiring..
When we are born, we have all these jumbled up neurons that haven't made any connections.. and (from what I've gathered through the years) there is die-off of neurons that aren't being used. As babies learn, the neurons (being used) develop the connections and live.
Therefore I am assuming that a baby will never develop Phantom Limb syndrome and that is relegated to people with hard-wiring for the limb in place. I could be wrong.
(on a side note...) this die off may explain why many of us have a very difficult time learning languages and developing things like perfect pitch. The Asian culture, in particular the Chinese, have a much more tonal sing-song language and therefore, their neurons (as children) develop the wiring, and don't die off (of course this is just conjecture) and viola, they have a higher tendency to develop perfect pitch. I love
Radio Lab, here is their perfect pitch segment
They also have a segment on
Phantom Limb Syndrome.
When I stated that if a babies limb was chopped off, I assumed everyone would understand that the brain would be setting up it's neural structure in this time. I should have been more clear.
I must admit it has been a long time since I've read Oliver Sacks and my brain books so my memory on all this is quite fuzzy.
I do believe that science is revealing that the brain is much more plastic then originally thought, and that neurons do come back (to some degree) after being damaged.. HOWEVER, if the specific neuron set that governs a certain thing (for example speech ) if
they die off.. They can't spring into being.
Mike,
you stated
Do you have a link to said article? I'm still thinking that we aren't "reading" anyone's mind. We can map minds, we can build AI brains.. but I'm really having a difficult time with this mind reading issue..
The video you posted of the study of where people could eventually activate the image they wanted to see (through thought) that was pretty awesome, but it leads me to ask.. how did they CHOSE what they wanted to see?
I think the problem with the "mind-reading" issue is that, you would have to "map" a persons mind to be able to read it. So the idea of the military engaging the enemy with their mind-reading helmets is silly, because they would not have been able to sit their enemy down in a chair and "map their brains" over god knows how many experiments and how much time. Then they have to understand the person emotionally, and understand their emotional motivators... has their been trauma in their past that makes them act a certain way? If you know anything about somatic therapy you really begin to wonder if we keep everything in our brains alone.
I don't think it is realistic.
As for the other awesome video of the 6 second decision time...
Your asking a person to make a random decision to press the right or left button.. Obviously there is alot more activity in that decision then we would think.. but what if you introduce another element.. for example, what if there was a screen in the mri machine that would blink red or green and you would have to press the right button for red and the left button for green... and they asked you to do that fast.. what happens then?
How would you view a persons brain and decision making abilities in a sparing situation?.. when you are reacting to another persons movements.. decisions are made, but they have to be made (obviously) very fast. I wonder if a fighters brain would have different decision making activity??
