How the brain learns from mistakes
 

Interesting :)

I think this article is somewhat uninformed. I don't see the relation between the cerebellum (coordination of movements) and schizophrenia and autism ... involving the entire brain and mostly the cerebrum.

P.S.
If you don't want to encounter the latter diseases, I suggest staying away from Aluminum, Fluoride, and Mercury.

Before i Graduated and entered the Master in Mech Eng, I studied Medicine ( did not finish though... ) and the knowledge that I have of neurophysiology points to the fact that connections between neurons are strengthened as a response to their frequent use... there is some sort of logistic growth in signal stregth as a feedback to the use of the related connection.

This occurs at synapse level, with progressive adaptation of the threshold for release of the associated neurotransmitter ( mostly acetilcholine )

But a "large scale" learning also occurs...

There is a known algorithm in artificial Neural Network training called "optimal brain damage" :



The network starts as a massive parallel redundant system, in which the redundancy of some connections is progressivly reduced : The strategy is to keep only the connections who contibute more for the desired network behaviour.

This is based on physiological observation of neuroanatomical changes caused by learning ( i.e. large scale effects ) not neurohistological changes ( these are only responsible for short scale effects )

@Aluminum, Fluoride, and Mercury

Don't eat at restaurants as you never know when they use aluminum pans, don't drink the tap water, and don't live anywhere or eat anything as mercury is almost everywhere and in everything we eat... mainly fish. Just don't eat fish.

Also don't touch your receipts because of the highest levels of BPA poisoning.

And take off that foil hat its aluminum !!111

Ah, almost forgot, Teflon as well ... very toxic, and they admit to it.

That's it, I officially quit /General...I can't take the bashing of "you couldn't possibly be 'free'" anymore!

I get it: everything is predetermined, life is just a series of causally related events, "conscious will" is an illusion, everything is meaningless. You don't have to remind me; I have a hard enough time dealing with the hard facts. :mad::cry:

EDIT: Okay fine, I don't really quit /General, but I'm still depressed...

Freedom vs Randomness is a matter of scale of analysis, scope... small vs large, very fast vs eternity... :)

deal with this in a ... Zen Fashion... we're all falling leaves...

At quantum level ( very small, very fast ) things are random, at Astronomical level, things are deterministic... we are all at the quantum scale of some scale much bigger, time and space-wise, than ours... so... are we really predetermined within the reach of our scope, within the grasp of what our measuring devices can grasp...??!!

This can be argued the other way: is quantum indeterminacy really so indeterminate, or are we just (currently) unable to determine the mechanics behind quantum events?

Anyways, sorry for dragging the thread so far off-topic. People will take their opinion for granted; whether it's on the free will side or the determinism side, so be it.

I guess I just really need to learn to STFU about my own dilemmas. :(

Huh ? I don't think you get it, I'm saying, yes you can change your future, it's your choice what to do and who to believe. It's best to believe the truth and what makes sense and not just what people say.

Oh, NO!!! Not more of the "I'm not free! I'm a slave to quantum physics!" male cattle excreta. Aaaaaaaaaaaaaaargh!

Reject quantum physics, free your mind !

and reject God(s)
and reject astrology
and reject anything that tells you that you're ONLY a machine/miserable sinner/puppet/pawn/patsy/etc.

It's curious that someone would have written a program such as yourself to be depressed by these things...

Absolutely !

Is that supposed to be a joke or not?

Because I believe it and think it's true.

I don't think it was a joke, I mean, yeah it is true ... even if it was meant as a joke ... which I don't think so.

I wanted to ask this question long back to all the atheists, since you don't believe in God(s) then in times of misery whom do you remember? I mean to whom your heart cries for help? What comes to your mind when you are in the jaws of death and have a narrow escape?

@Anisha

Please...let's not turn this into a big atheism vs. religion/spirituality flamewar. Not that your post is inflammatory, it's just that I'm worried that other people are going to see that and turn this thread into a big debate.

Really, I'm sorry I even posted what I did; it was one of those "knee-jerk" reactions, i.e. this thread's topic struck a nerve so strongly that I didn't think before posting. :redface:

Maybe it's just mankind's ideas of god(s) I don't believe in. And if anyone gets comfort in times of distress from belief in god(s), that's OK.

You didn't understand the question perhaps.

I've been close to death many times (mostly because of disease), and I never prayed to anyone. I relied on myself, I believed that I had the strength to defeat anyone and anything ... and I made it through. Along with, of course, antibiotics and some good doctor's advice :)

Perhaps, perhaps not? The only time I've been close to death was in infancy (about 15 months old(?)), from double pneumonia. I don't know for certain if my disbelief would change if I was dying, but I doubt it.

My father says that YOU are what YOU think you are. Perhaps the disbelievers are the strongest people around since they know that they don't have anyone with supernatural powers to turn to, in distress, so they bring out their best in crisis rather than praying and waiting for some God to show miracles!

I am afraid, I might turn into a disbeliever now :eek:

(If "turn into" is not a correct/perfect combination here, please correct it)

Well, it's up to you what you believe ... I guess some people need to believe ... I don't.

And here I thought this thread was going to be how people learned. Before the Believers and non-believers take this off to where I don't care any more I'm reminded of how I heard people learn.

1 - Some people learn by reading.
2 - Some people learn by watching.
3 - Some people have to pee on the electric fence and find out for themselves. ;)

With propper training you would be Buddhist, and Samurai... :)

This is the Fortress thought.

Hey everyone... LOL How the brain learns from mistakes... the immutable truth is that many people make the same mistake over and over ad-infinitum... this condition has a very scientific title... STUPIDITY

ps Of course its not stupidity when its my extra special favourite, (me) when I do the wrong thing over and over again its wisdom.

McCode suck the juice out of some Pomegranates and I bet you feel better in the next twenty years.

Pomegranate juice is a panacea.
