Brain Stem -
coordinates the muscles that you use for action such as running, walking, or playing the piano. It also helps control your balance and maintain posture.
It regulates all your thoughts and actions. There are many sections of the cerebrum that control what you hear, smell, how you move, how you think, write, talk and express emotions.

Impaired memory, thinking and behavior; sometimes confused with aging
Chronic disease of CNS; Caused by destruction of myelin sheath – means impulses (signals) slow down or can’t get through
Brain cells die because of lack of oxygen; Brain attack; blood vessels can clog (thrombosis) or burst (hemorrhage)
Movement disorder; varies from not being able to walk to being able to move more easily;
Degenerative disease characterized by Tremors of the limbs of the body
