Neural communication the fact that info systems of humans and other animals operate similarly allows researchers to study simple animals, yet learn about humans as well though it varies in complexity, most nervous systems follow the same principles. Myelin is laid down up to about age 25; neural efficiency, judgment, and self-control continue to grow. Brain is more complex than computer, but slower at executing simple responses.
