jimNov 2, (THAINDIAN NEWS) A recent research has given evidences that our darkest and the most traumatic memories can be permanently removed. The research was conducted by the Johns Hopkins University School of Medicine and Howard Hughes Medical Institute and they published their research in this weeks’ issue of a renowned scientific magazine.

The research was reportedly conducted on rodents and it said that removing the protein cells from that area of the brain which is responsible for recalling fear, can actually delete those fearful and unwanted memories. Whereas the previous researches have focused on the behavioral means to overcome the fear and trauma involved in the retrospection of fearful memories, the new research focused more on the chemical procedure involved in it. The amygdala may be regarded as the emotional seat of the brain. It was found in the rodent, that after aloud bell was rung, certain cells in the amygdala conducted more electricity in the brains of the rodents, conditioned to react fearfully to that loud sound. A deeper research then stated that there was an increase in calcium-permeable AMPARs in those parts of the amygdala after the rodents got scared and it continued to stay for more than 48 hours. Therefore, the simple conclusion that was reached was, the removal of these AMPARs can remove the fear from the brain cells. However, the research went a step ahead to discover that by resorting to some protein-controlling medication, these fear can be permanently removed.

Richard L. Huganir, PhD., professor and director of neuroscience in the Johns Hopkins University, who was involved in the research, said that it might sound like a science fiction, but this treatment can be adopted to recover from post-traumatic stress syndrome due to fearful memories of rape, war, violence etc, which other behavioral therapies fail to treat.
