believed that This stress hormone is associated with bad memories, and, on the idea of \u200b\u200bresearchers, controlling its level, could weaken the unpleasant impression are stored in the brain, reports Kompyulenta.
The experiment involved 33 people who were supposed to memorize the history, production from neutral and negative events. Three days later, after they were forced to memorize the story, the subjects were divided into three groups: some received a dose of metirapona (funds, the vast cortisol synthesis), another group was given the double dose of this medication, and the third - a placebo.
After receiving metirapona experimental asked to recall and retell the story memorized them. Then they were again to recall the same story, but four days after taking the drug, when metirapon has been removed from the body.
who receive a double dose of medication, could not recover in the memory of negative episodes of the story, but the neutral pieces recalled with ease. What is more surprising, the same effect was observed after four days, when metirapona the body was gone, and cortisol levels returned to normal.
These results forced a new look at the hypothesis that memories in the brain can not be modified by intervention outside.
the contrary, it appears that a single biochemical effects in the actual moment of remembrance has blurred some "Undesirable" events of neuronal storage.
scientists intend to continue to study the hormonal inhibitors that can affect memory. This will help both clinicians who deal with post-traumatic syndrome, and researchers studying the general processes of memory formation.
