their spinal cord
their peers
Explanation: The brain's "white matter" enables nerve signals to flow freely between different parts of the brain. In teenagers, the frontal lobes have less white matter (myelin) than adults. Myelin is a fatty coating that helps nerve cells communicate. The myelin insulation won't be complete until they reach their late 20s.
