Answer:
The cerebrum
Explanation:
Deep down in your brain, there's an area called the substantia nigra, which is in the basal ganglia. Some of its cells make dopamine, a chemical that carries messages around your brain. When you need to scratch an itch or kick a ball, dopamine quickly carries a message to the nerve cell that controls that movement.
The cerebrum controls voluntary movement, speech, intelligence, memory, emotion, and sensory processing. At the base of the brain, the brain stem connects to the spinal cord and is made up of the midbrain, pons, and medulla oblongata.
