How the hell do brains work?!

Ok, i was having this reallllyyy deep conversation with my mate. You know the ones, "why are we here", "are their aliens", "what happens when you die".. and we got talking about brains.. How do they work? You decide you want to move your arm up and your brain sends you electrical nerves to do this? So its electricity and muscle working which get people speaking and moving? Wheres the information stored that lets you remmeber words and calculate sums..

How did something evolve to have a brain? and if they are electric nerves then couldnt we make one seeing as we can harnace the power of electricity?

Im confused... and I appreciate you all arent brain surgeons, im just curious if you could shed some light.

you smoke a lot of pot, yeah?

used to yea but surprisingly me and my friend were perfectly sober at the time lol..

And yea I understand what your saying about the reaction to move away from a hot object but it was just the general learning of the brain etc which I found so interesting..

I really think scientists should do some more research into it to be honest.

What really did my head in was when my Physics teacher (god knows why he said it) asked us where we see what our eyes see?

That really got us going, it's basically a bunch of light turned into electrical signals that form an image somehow, it's getting me all twisted just thinking about it

through our eyes? ..

i dunno, but interesting nightfly, am getting quite confused to be frank but the brain is an incredible thing that is a fact

They just receive the light on the retina and then pass the electrical signals to the brain, so they are nothing more than receptors.

yea but we see out of our eyes. We dont see out of our brains do we?
