From childhood through middle age, the brain undergoes significant changes. One of the key changes is a decrease in gray matter, which is largely made up of neuronal cell bodies and is involved in processing information in the brain. This decrease is thought to reflect a pruning process, where unused neural connections are eliminated, making the brain more efficient. On the other hand, white matter, which consists of myelinated axons that connect different brain regions, increases. This increase in white matter improves the brain's connectivity and processing speed.
