The document appears to be a series of questions about brain structures and functions with the correct answers provided. Some of the structures and concepts mentioned include: - Reticular formation, which controls alertness, breathing, and heart rate - Medulla, which controls breathing and heart rate - Cerebellum, which is important for motor control like balance - Hippocampus, which is involved in short-term memory - Amygdala, which controls aggression and fear responses - Various brain imaging techniques like EEG, CT scans, PET scans, MRI, and fMRI.

2. “ I can activate your senses to a state of alertness. Who am I?”

3. Reticular formation

4. “ You never even pay attention to me. I control breathing and heart rate, but I never get any credit. Who am I? (You probably don’t even know who I am.)”

5. Medulla

6. “ You would never be able to walk across a tightrope if I was deficient in you. Who am I?”

7. Cerebellum

8. “ I help you remember things in the short-term. Who am I? (It would be rather ironic if you forgot.)”

9. Hippocampus
