WebbIn the first four years of life, the brain increases to 80% of its adult weight of 2.6 - 3.3 pounds (1200-1500 grams). Pruning is a key process shaping the brains of young children. Synaptic overproduction causes synapses to develop extremely rapidly. The pruning process refines these connections based on experience.
