Another Way To Erase Memories

amigoro writes "Neuroscientists have discovered that long-term memories are not etched in a stable form, like a 'clay tablet,' as once thought. The process is much more dynamic, involving a miniature molecular machine that must run constantly to keep memories going. Jamming the machine briefly can erase long-term memories." A few months back we discussed a similar removal of rat memories by a different method.

Erasing traumatic events is not helpful. Learning to accept and cope with a past traumatic event is. People that run and hide aren't people that we need around, we already have too many of them without the advent of memory wipes.

Juggling

[umbrellasd]

So your memories are a function of how many molecules you can juggle. But you are more than your memories. Even if I couldn't remember things that happened to me beyond a day ago, I would still have opinions and feelings about situations that occur each day. I wouldn't have specific memories to tie to current events, but I would still avoid some situations and be drawn to others.

Which leads me to wonder, where that "you" is stored and if that storage is "permanent" or easily disrupted. Is my knowledge of mathematics a "memory"? What about my general disposition? Can someone make me drop the "Don't murder people" ball and disrupt my a moral imperatives? That one happens pretty often, actually.

There's no permanence. Just an ever-changing approximation of whatever you envision yourself to be.

I'm going to have to disagree with you here. There are some cases where "accepting and coping" isn't an option. And I'm not talking about an in "Eternal Sunshine"-my-girlfriend-broke-up-with-me-and-I'm-r eally-sad type of way. I'm talking about cases where, because of bugs in the fear machinery, people's brains are in an error state that "coping with" can't reverse. Just as cells have normal parameters for homeostasis in which everything functions correctly, so do mental processes. In severe cases, we're not talking about just the psyschological realm. We're talking about gene transcription, protein levels, etc, that are outside of their normal boundaries, and that type of problem isn't easily (or even not so easily) helped by cognitive therapy and coping alone.

Yes, obviously rape victims should accept this fact and get on with life.

I can accept we have far too many people with a victim mentality; I can accept that this has a large potential for abuse. I can't say that someone who can't live a normal life because of a traumatic event in the past shouldn't get treatment. Yes it will be a very ethically complex drug even if it worked perfectly, but to deny all uses of the drug? I imagine it might also have some uses in military personel, but... yes, it's a very slippery slope.

Who are you to say that?

[spun]

Are you a psychologist? Do you know about current treatments and their success rates? Furthermore, who are you to say that we don't want others buying a treatment that might help relieve their suffering? Some types of trauma can not be 'accepted and coped with.'

What a load of authoritarian claptrap. You sound like the type of person who has had some small measure of success dealing with their own minor past hurts and now has THE ONE TRUE ANSWER for every human being on the planet. Good luck with that.
