Damage to the hippocampus primarily affects the ability to form new memories, as this part of the brain is essential for converting short-term memories into long-term memories. While other areas, like the amygdala and the cerebellum, play roles in emotion processing and motor control, respectively, they are not directly responsible for memory formation. Therefore, the correct answer is the hippocampus. ;
The correct answer is A: hippocampus. Damage to this part of the brain impairs the ability to form new memories, as it is crucial for turning short-term memories into long-term memories. Other brain structures like the amygdala and cerebellum play different roles, but they are not primarily responsible for memory formation.
