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.

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.

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.

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