Question

Quizplus · Accepted Answer

The cerebellum plays a key role in balance, coordination, and spatial reasoning, as well as in discriminating between different sensory stimuli. Thus, Darnell's deficits in these areas suggest that his cerebellum has been affected by the head injury. The brain stem, midbrain, and occipital area are also important for various functions, but their impairment would likely result in different symptoms. For example, damage to the brain stem could affect breathing and heart rate, while damage to the occipital area could affect vision.
