Sample QuestionJohn is a 57-year-old man who has always been a very heavy drinker, often consuming 2 pints of whiskey per day, for many years. Upon the urging of his wife, he decided to seek medical attention for help with problems with his gait, which has steadily worsened over the past several months. He noticed that he now needed to stand with his feet far apart in order to maintain his balance and that he waddled when he walked. The doctor who evaluated him tested his memory and speech carefully, as well as his cranial nerves, and was unable to find any deficits. There was no weakness, sensory loss, or abnormalities in his reflexes. When asked to touch the doctor's finger, then his nose, John missed his nose slightly, but rapidly corrected the movement on both sides. When asked to slide his right heel down his left shin, his heel slid sideways and clumsily across the bone until it reached his ankle. The response with the left heel was similar. When asked to walk, John walked with his feet very far apart. If he attempted to walk in a tandem fashion, with one heel in front of the other toe, he began to fall, and the doctor needed to catch him. The doctor ordered an magnetic resonance imaging (MRI) of John's head. The region of the affected area is associated with which functional division of the cerebellum?
