: '''Mirror Neurons''' → Neurons that fire both when an animal acts and when it observes the same action performed by another (possible basis for empathy).
: '''LTP (Long-Term Potentiation)''' → The strengthening of a synapse based on recent activity; the cellular basis of learning.
: '''Blood-Brain Barrier''' → A highly selective semipermeable border that protects the brain from toxins in the blood.
: '''Cranial Nerves''' → 12 pairs of nerves that emerge directly from the brain, controlling everything from eye movement to heart rate.
