Worksheet – Brain Functions
Name: ______
1. Describe how and MRI and a PET scan are different from each other.
2. Which structure, if transected, will prevent the cerebral hemispheres from communicating with each other?
3. You are walking by the perfume counter and the perfume lady sprays a sample on you. Instantly, you are flooded with memories of your one true lost love as you smell the odor. You begin to cry at the emotions you still feel. What part of your brain has been activated?
4. You are at the emergency room when the ambulance calls in about a patient they are bringing you. EMS states that the patient is conscious and comprehends what they are telling him but cannot make his mouth muscles work in order to communicate. What area do you expect to find damage in?
5. This is the part of the brain whose disruption causes you to stumble and slur your speech when affected by alcohol by inhibiting coordination.
6. What area if damaged results in aprosodia?
7. What area if injured results in irreversible coma?
8. What area if injured will result in death?
9. What area causes us to blink and turn our head if something is coming toward our eyes?
10. Injury to this area will cause personality & motivation changes - lobotomy used to be performed to treat mental illnesses that affected personality.
11. This area regulates body homeostasis -such as food, thirst, sleep, body temp.
12. Injury to this area would cause you not to be able to type or to ride a bicycle automatically but you would be able to relearn.
13. This area is your biological clock - helps give you jet lag - affected by light – long gray days in winter can cause seasonal affective disorder (type of depression) because this area doesn’t get enough light input to produce the correct balance of chemicals.
14. If this area is damaged, it would leave you a complete imbecile unable to comprehend your surroundings even though all your other regions would be working correctly.
15. What area coordinates your arms swinging with your legs moving and other stereotypical motions?
16. You go to a rock concert and sit right in front of the speakers. Which part of the brain will attempt to help protect your little ear bones by tightening up your eardrum in reflex action to the incredibly loud noise?
17. If I run into the overhead, which part of the brain would tell me that I ran into it with my hip?
18. Given the above example, which part of the brain would integrate past experiences with the overhead, analyze the data, and tell me to walk farther away from the overhead next time?
19. When you spend the night at grandma’s house, you always have trouble sleeping and wake up frequently. This is because the ______only filters out familiar & repetitious noises.
