Question

Quizplus · Accepted Answer

The cerebellum is the brain structure responsible for fine motor coordination, including hand-eye coordination. Alcohol depresses this area of the brain, making it difficult for individuals under the influence to perform tasks such as touching their nose with their finger. The other brain structures listed do not play as significant of a role in this motor coordination task.
