Scientists reveal how the brain maintains useful memories

Scientists have identified specific groups of neurons in the medial prefrontal cortex that develop codes to store relevant information from multiple experiences. Over time, these neurons lose less important details unique to each experience. The findings provide new insight into how the brain collects and stores useful knowledge.
