Your memories can be selectively erased.

Famous experiments by neuroscientist Karim Nader demonstrated that each time you remember something, you demolish the old memory and recreate a new one.

In order to store a memory, a protein structure needs to form in the brain.  When rats are given a drug that disrupts this protein formation while they’re trying to form a memory, the rats are unable to learn.  Now here’s the weird part.  Once a rat becomes an expert at some knowledge — like knowing that a certain sound precedes a shock — and researchers inject the drug while he’s trying to recall the memory, the memory is erased permanently.  The rat returns to the same state of ignorance he was in before he ever learned.  No other memories are harmed by the drug, only the memories the rat is trying to form or recall. That means the protein that encodes the memory is being rebuilt every time the rat accesses the memory.

A man who had a tiny tumor cut out of the cortex near the frontal lobe of his brain seemed fine at first.  He passed all intelligence tests and retained all faculties.  But once released to daily life, he was paralyzed by an inability to make the simplest decision.  Sitting at his office desk, he spent twenty minutes deciding whether to use a black pen or blue pen, carefully thinking through every implications of each option

This page is pretty amazing actually

The left hemisphere is in charge of language.  The right hemisphere is in charge of visual imagery.  When you flash an image of a spoon to the eye that corresponds to the right hemisphere, the patient with a cut corpus callosum will say he sees nothing.  When asked to grab the object using the hand that corresponds to the right hemisphere, the patient will grab the spoon they just said they couldn’t see, yet still be unable to say what they are holding.
Also amazing, imo.

Ah... i like what ppl can think about the brain and such, kinda funny Tongue

The first part with the memories is not really impressive nowadays, it's even kinda easy, we know a lot more about receptors and such, " almost " easy to do such things Tongue

And i'm learning how your brain is made atm ( the differents zones and such ), and that's a **** mess Tongue

Lol, well I've never heard about selective memory removal. Weird actually, you'd say such stuff would be pretty well known... At least in some movies (and i mean movies better than totally spies on jetix Tongue). And why isn't this used against traumas? Or maybe it is, but I've never heard of it.

@Andrew: not exactly, that's mostly a dumb's brain ( because of **** campers Grin )

@Luc: it's well known indeed... in theory, it's not yet easy and usual in pratic, kinda really expensive, there's a lot of possibles troubles.
We know how it works, but making it works in humans safely is another problem Tongue

Sorry for doublepost, but you should post faster Tongue
Anyway, this is a track of my mouse movements between around 3pm today and now (21:45):

(mostly been browsing).

If you wonder about some horizontal lines, I have mouse gestures in my browser. So to go back or forward a page, i use a horizontal mouse movement Wink

edit: and some stats:
