What should we be allowed to forget?

Should we be dampening the emotional aspect of memory?

Two decades ago, scientists began to wonder if they could weaken traumatic memories by suppressing the hormonal rush that accompanies their formation. They turned to propranolol, which was already on the market as a treatment for hypertension and blocks the activity of hormones like epinephrine and norepinephrine….Next, in 2002, neuroscientists reported that emergency room patients who took propranolol within 6 hours of a traumatic event were less likely to experience the heightened emotions and arousal associated with PTSD one month later, compared with people who took placebos.

The hitch was that in order to interfere with memory consolidation, propranolol needed to be given within hours of a trauma, long before doctors knew whether someone would go on to develop PTSD. But around the same time, studies began to show that memories can once again become fragile when they are recalled…Perhaps, researchers hypothesized, propranolol could weaken emotional memories if PTSD patients took the drug after they conjured up the details of a painful experience. By blocking the effects of norepinephrine and epinephrine upon recall, propranolol might dampen down activity in the amygdala and disrupt reconsolidation.

I liked this comment someone left on the article:

If the memory of my trauma were to be removed, I would make no sense to myself.

If we could edit our memories, what is important to who we are? Is there a threshold of pain beyond which we should not be forced to endure our entire lives? What was adaptive one hundred thousand years ago may not be adaptive in modern society.
