Yvette was diagnosed with Lyme disease and is having difficulty with balance, walking a straight line, and simple motor movements. Which of the following areas of her brain would you suspect is being affected by the disease and causing the above mentioned symptoms?
a. the cerebellum
b. the reticular formation
c. the hippocampusd. the corpus callosum

The cerebellum is the hindbrain and controls motor functions. It integrates sensory input from other parts of the brain and the spinal cord to fine tune motor control. If someone is having difficulty balancing, walking, or moving, they most likely have an abnormality in the cerebellum. The answer would be A) Cerebellum.

The other answer choices would not account for the listed symptoms. The reticular formation is involved in consciousness and arousal, the hippocampus plays a major role in memory consolidation, and the corpus callosum consists of nerve tracts that connect the right hemisphere of the brain to the left hemisphere.
