Electric

[Botsareus]

I was just thinking: If we get a pritty realistic electric model going then we can model some pritty realistic neural networks, Its going to be almost the same as the real thing.

[Ulciscor]

We can model neural networks already, it's just v. complex....

[Numsgil]

Um, you don't need electricity to model neural networks.  The two are quite unrelated.

[Botsareus]

Key word: realisitc nerual networks...

The human brain works on electrsity for all I know...

It's just an idea I put up there , just in case...

[PurpleYouko]

Yes the human brain works on electrical impulses but they are a secondary function.
The brain learns by making new physical connections between neurons. The electricity is just the messenger that carries bits of information down the connection.
It isn't necessary to have any laws of electricity present to model neural nets. It is far easier to completely ignore the electricity.

[Numsgil]

Technically it's not electricity.  It's potassium ions I think.  Anyway, much different but still related to what we think of as electricity.

[PurpleYouko]

Well electricity itself isn't what most people think it is.  B)

It's amazing how few people really know what it is.

[Numsgil]

Electricity is the passing of electrons (tiny tiny quanta of energy) via excited charged conductive particles, generally metals such as iron, etc.

Our brains pass potassium positive ions (if not potassium, then maybe sodium), which are much, much, much larger than electrons, and have the oppositive charge.

The effect is indeed the transmitance of charges.  But the mechanisms are so entirely different.

[Zelos]

but cause its electrical charged it is effected by "normal" electricity and magnetism, parts that have been badly hurt are acctualy able to repair it self in a increadeble rate, it aint that much but huge for the brain, when its stimualted by magnetism.

[Numsgil]

Um, I'm going to say that's a load of horse hooey.

All that new age magnets-around-my-wrist things are just bull.  There has not been any scientific study able to link magnetism/electrical fields and physiological effects.  (Except for that electromagnet at Fermilab, Illinois, which can produce a field strong enough to pull the iron from your blood.  That one definately has some physiological effects.)

[Botsareus]

haha, I like that one.

[Zelos]

this has been scientifical studies about this, they took away parts of a rats brain, and after it exposes it for magnetic fields and then they open him again and saw that the body have repaired some of the damages the removal of the part caused, and usualy brain dont repair it self

Primary research does not scientific fact make (odd grammer composition on purpose, I realize that may look a little strange on paper...)

nor is something not true simply because we don't yet know about it.
we don't know what we don't know.
remember ...
the earth was once flat and the sun revolved around us. ;)
discoveries are made when one is able to suspend one's disbelief
long enough to take a look at what one doesn't already 'know'.
knowledge is not static, but a dynamic, ever expanding process.
conjecture, speculation, theories ...
are only tools ...
maps that are subject to being rewritten ...
menus that will be altered.
our perception of reality is no more than soup de jour.  ;)

true scientific method of inquiry ...
is about remaining as open/flexible/malleable/adaptable as possible ...
'especially' when we begin to think we 'know'.

its not a fact, but it see, to happen all the time, but who cares. and griz ure im begging you stop wrting like that, it hurts the eyes. AAAAH M Y EYES!!!
