Memory-True or False : In the 1980s in the United States, there were many cases of adults who suddenly remembered, with the help of a psychologist, things that had happened to them in childhood. These memories had been repressed held back for many years. Some of these newly discovered memories have sent people to prison. As people remember crimes (such as murder or rape) that they saw or experienced as children, the police have re-opened and investigated old criminal cases. In fact, over 700 cases have been filed that are based on these repressed memories. However, studies in the 1990s suggested that many of these might be false memories. At a 1994 conference at Harvard Medical School, neuroscientists discussed how memory is believed to work is known It that small pieces of a memory (sound, sight, feeling, and so on) are kept in different parts of the brain; the limbic system, in the middle of the brain pulls these pieces together into one complete memory. But it's certain that people can "remember" things that have never happened. Even a small suggestion can leave a piece of memory in the brain. Most frightening, according to Dr. Michael Nash of the University of Tennessee, is that "there may be no structural difference" in the brain between a false memory and a true one.
