Canadian scientists have learned how to erase bad memories

on Mon Jun 26, 2017 9:11 am
The researchers were able to precisely "erase" one of the few memories mollusk that has the potential to help people with post-traumatic stress disorder (PTSD)
This writes  Science Alert .

A team of scientists from the US Medical Center Columbia University and Canada's McGill University analyzed neurons kind of shellfish Aplysia (sea hares) to test the hypothesis that explains why memories of incidents that brought bad experience can cause the most concern.

Scientists have shown that long-term memories cellular counterparts in shellfish can be removed independently. Thus, blocking the action of different subspecies protein (M protein) that is involved in creating and storing long-term memories. Selective blocking of a protein led to the removal or neasotsiatyvnoyi associative memory.

"One major focus of our current research is to develop strategies to address the problem neasotsiatyvnoho memories that can affect the brain during traumatic experience without compromising associative memories, that can help people make informed decisions in the future" - said one of the authors of the study , Samuel Shaher.

In further studies, scientists at these preclinical models more precisely understand how and where the molecules are produced and protein M.

"Erasing memories has the potential to alleviate PTSD and anxiety disorders by removing neasotsiatyvnyh memories that cause inadequate physiological response", - underline the researchers., Original in Ukrainian / на українському
