Brain Function Being Dependant on Co-ordination

The idea that how we use our brain comes down to how we can co-ordinate our energies...

Basically we can quite easily grasp the idea of moving something.
Basically we push or pull one or many muscles...

The key to movement, and activation (I believe) comes down to how we co-ordinate...

So how is it done?

You locate an area... Possibly through something happening to you reminding you of that area...
You would realise it's functions, and enact a movement or activation (or many small movements or activations) around that area...

But, still how did we locate the area?

Well, to put it in perspective...
The mind is constantly co-ordinating, constantly updating and forever applying new events to previous approaches to produce ever new self-enacted mental and bodily events...
The new sensation comes into contact with the application of an older sensation, changing the numbers and figures, which results a new application...

Okay, I understand that much...

But, is the co-ordination of the new application (in the areas it uses) like triangulating a radio signal?
Can you add anything to the equation?

I guess the most important part of how this works (and understanding it) would be finding out how we use certain areas of the brain for different functions...
We may also be able to reassess how the mind works. For example, the idea that certain brain areas do perform different functions, but the placement of these areas comes down to how we co-ordinate ourself. This would be in opposition to the brain areas been placed simply by evolution of primary function (that being the area coming to be in that place from the general flow, or something of that nature).

One other interesting thing to consider would be how one area of the brain can compensate for another to help perform tasks the first area could no longer perform...
