I just want someone to explain to me a bit of science. I don't understand how our mind tells our arms to move, legs to move etc. For a bit I thought it might be something like if we look at our arms, they move, etc, but this cannot be the case (blind people can bend things).
I guess my question is: How does our brain tell each part of the body to move? Is it a code? Is it something we are born with? How would we be born with such knowledge?
I know it might sound like a stupid question, but it's been on my mind lately.
Also, does anyone else think we're just a current of electricity/energy that uses the body as a host? Just wondering

I guess this question really got me thinking about the first one (how are arms move). I was thinking about if we found out how to transfer our 'energy' or our conciousness to a machine somehow..could we then teach our mind to work with parts of a machine the same way it works with joints, eyelids, etc?
I hope I made sense. This is a little over my head, but I love to think about it.
