At the NeuroCure Institute, scientists have recently discovered something that would be straight out of a plot of a science fiction novel: the ability to choose particular memories to erase from the brain. These scientists experimented on mice through optogenetic techniques to target specific memory pathways in mice. The findings showed that the critters lost recollection of specific traumatic experiences while keeping other memories intact. 

People with traumatic memory disorders, such as the commonly known PTSD, struggle with traditional methods of treatment. They find it very troubling to have these unwanted recollections of their difficult memories. Therefore, this technology would relieve millions by forcibly shutting down these recurring traumas from their brains.

This is a fascinating breakthrough. Nevertheless, various ethical issues need to be addressed. Critics argue that memories play a critical role in defining a person’s identity. They are worried that selectively erasing experiences would stunt the learning from one’s past mistakes and the growth of one’s character. There is also a concern about this technology being misused. What would happen if somebody applied this technology to erase memories of a crime?

This technology is still in the early stages and is not ready for human use. This discovery highlights an important idea. Learning about psychology goes far beyond simply studying the mind and understanding how it is being shaped. Finding a balance between innovation and maintaining ethical integrity is the key to the future success of this technology.
