Brain stores three copies of every memory, new study says

A groundbreaking study from the University of Basel’s Biozentrum has unveiled that the brain employs three distinct sets of neurons to store a single memory, enhancing redundancy and stability in memory retention, New Atlas reported yesterday.

Researchers discovered that early-born neurons, which develop first, initially struggle to retrieve memories but strengthen over time. Conversely, late-born neurons provide a robust initial memory storage that gradually fades, while middle-born neurons maintain a higher degree of stability.

This discovery not only sheds light on the intricate workings of memory formation but also holds significant implications for treating trauma. The research suggests that understanding how memories are stored could lead to innovative approaches for modifying painful memories, particularly for those affected by traumatic experiences. By leveraging the brain’s inherent plasticity, scientists may develop strategies to help individuals access memories thought to be lost or to alleviate intrusive, distressing recollections. The findings were published in the journal Science, marking a pivotal advancement in neuroscience.
