Discover the essential process of neural pruning in brain development, distinct from creating new connections, managing neural waste, or increasing brain weight. Uncover how this natural "clean-up" refines our neural network, making our brains more efficient in processing information. Explore the impact of neural pruning on cognitive growth and the interaction between genetics and environment in brain development.
