A new study in Nature Communications reveals that the brain doesn’t begin empty — it starts highly connected. Scientists studying the hippocampus found that early neural networks are dense and somewhat random, especially in key cells like CA3 pyramidal neurons.
As the brain develops, these connections are pruned, becoming more efficient and organized.
This “start full, then refine” model suggests that early overconnectivity helps the brain quickly integrate sensory information and build memories. Over time, unnecessary links are trimmed, shaping a more precise and functional neural network.
