„Fantomele” din creier care păstrează amintirile uitate. Ce au descoperit cercetătorii

Researchers found that forgotten memories in fruit flies can persist in a hidden state and be reactivated by specific cues, but this process may also lead to false memories. The study highlights the complexity of memory retrieval, showing that contextual cues are essential for recalling forgotten experiences. As flies forget, the memory trace fades, while another hidden trace becomes active, allowing the memory to influence behavior again when the right cues are present. This suggests that memory is reconstructed rather than simply retrieved, and further investigation is needed to understand the underlying brain processes.
