A new study in Nature Communications reveals that the brain’s memory center, the hippocampus, doesn’t begin as a blank slate. Instead, it starts densely wired – a “full slate” – with highly connected neurons.
Researchers found that early networks, especially in the CA3 region, are initially random and overactive. As the brain matures, these connections are pruned, becoming more precise and efficient.
This explains why early memories are often vague – the system is active but not yet refined. Over time, pruning sharpens memory accuracy, helping form clearer, long-lasting experiences.
