The researchers at the University of Toronto have discovered a way to find and erase traumatic memories, a development that could help many get rid of their bad past experiences and even drug addiction. The study discovered that specific memories are concentrated in certain neurons of the brain, and targeting these cells could turn off the painful recollections in an individual.
Post Traumatic Stress Disorder is one of the major health concerns among soldiers and leaves an invasive, disruptive impact on their everyday life. Some observers are skeptical about the ethics of this medical breakthrough, as they believe erasing the memories could do away with a vital part of a person’s identity, writes Mirror.
Warning of the potential downsides, Dr. Sheena Josselyn, Associate Professor Department of Physiology, says deleting “fear or threat” memories might also eliminate the alert system that prevents one from repeating the same mistakes, notes The Telegraph.
