Neuroscientists at the Friedrich Miescher Institute for Biomedical Research have identified that forgotten memories can persist as "silent memory traces" in the brains of fruit flies (*Drosophila melanogaster*).

Published in *Nature Neuroscience*, the research demonstrated that while an association between an odor and an electric shock may appear to fade behaviorally, the information remains accessible. When flies are returned to the original environmental context, such as specific lighting or textures, the memory can be reactivated. 

Findings also indicate that this retrieval process can lead to the formation of false memories, where flies avoid harmless scents based on the training context. Researchers suggest this mechanism may allow for flexible adaptation, though they note that these specific results from fruit flies cannot be directly applied to humans.

Swiss researchers found that forgotten fruit‑fly memories persist as silent brain traces and can be revived by contextual cues, though retrieval may produce false memories.
