However, researchers recognize its potential in revolutionizing mental health treatment and alleviating traumatic memories. Nevertheless, caution is necessary when tampering with memories, as they form the core of our identities.
Sheena Josselyn, a memory and learning researcher at the Josselyn Frankland Lab in Toronto, Canada, emphasized the importance of minimal intervention. The brain’s complex workings are still not fully understood, but recent studies have shed light on how memories are formed, stored, and retrieved. While erasing specific memories, creating false memories, or mitigating the trauma associated with distressing memories is possible in snails and rodents, these methods have not been achieved in humans.
In 2014, MIT researchers Steve Ramirez and Xu Liu successfully implanted a false memory of receiving a shock in a mouse’s brain. By activating specific neurons through laser stimulation, the researchers induced fear in the mouse when placed in a particular box, even though no actual shock had occurred. This breakthrough opened doors for further research on memory manipulation.
More recently, researchers at Columbia University Irving Medical Center and McGill University discovered the potential for eliminating distressing recall of traumatic memories. By understanding non-associative memories and their impact on trauma-associated disorders like PTSD, they aim to reduce the triggers that cause fear and distress. Traumatic memories tend to linger in the brain, making it challenging to tackle them effectively.
Samuel Schacher and his team at Columbia University achieved selective memory erasure in snails, offering hope for future research in targeted memory manipulation. Similarly, Richard Huganir at Johns Hopkins University demonstrated the reduction of fear associated with traumatic memories in mice by removing specific proteins from the brain. Although these studies are promising, no drugs exist to achieve targeted protein removal in humans.
Memory manipulation could outperform exposure therapy, a method commonly used to tackle traumatic memories, as it ensures the emotional content of the memory is erased, leading to fewer relapses. Josselyn’s lab explores how specific brain cells can be targeted to erase fearful memories in mice, providing a potential breakthrough for trauma-induced disorders.
Severe trauma often leads to post-traumatic stress disorder (PTSD), where triggers associated with the trauma exacerbate the suffering and distress. By unlinking triggers from traumatic memories while preserving the memory itself, individuals with PTSD can experience relief from debilitating episodes.
Memory manipulation research not only offers possibilities for memory erasure but also sheds light on memory dysfunction. Understanding how memories are formed, stored, and retrieved could aid in treating conditions like Alzheimer’s, dementia, and amnesia. Unlocking forgotten memories in individuals with dementia is a conceivable outcome of this research.
Despite the potential benefits, ethical and medical concerns loom large. The notion of enhanced or suppressed memories raises questions about personal identity. Moreover, memory manipulation could lead to dissociative identity disorder or other unforeseen consequences. Therefore, caution and ethical considerations must accompany any advancements in this field.
