Brain Power Worksheet

This Exercise is to be turned in at Test #1

Follow instructions and answer the following questions using the BrainPower tutorial. 

Note that when you are asked to click a brain area you must click VERY NEAR its guide number (and within the brain region to which that number applies). If you are not careful to do this, you will get bad information, especially when the brain region in the question is small or narrow. 

Follow instructions carefully, but use common sense; the program can only give the information you want if you tell it to do so by using the right pre-selection buttons, and by clicking in the appropriate places. If you don't use the program right, you will either find this worksheet frustrating or have wrong answers.

Remember, you can not hurt the program, so play around with it for a while, and get used to buttons, brain images and guide numbers. When you feel you grasp how the program works, then follow the directions and answer the questions below:

For maximum points be very thorough and write the maximum amount of correct information.

_______________________________________________________________. 

7. What is the deep groove, between the two hemispheres? (Area 6)
_______________________________________________________________.

8. Click on "Structures." 
Read about areas 4, 5, 6, 7, and 8. Then, pre-select the Gyri/Sulci button and read about them again. 
Answer these questions, going back over the brain areas again if necessary:

10.  Goto Image # 5 (The Cerebral Blood Supply). Read all the info you can get using the Structures and Connections buttons (clicking in the middle of the image will get you there). 
Which one of these would happen to you if the Anterior Cerebral Artery (not shown) were to get completely blocked off by a blood clot, eliminating oxygen supplied to the front of the brain? 
_____A. You would go blind.
_____B. You would only lose some coordination and memory.
_____C. Not much.
_____D. You would be both paralyzed and unable to speak normally.
_____E. You would have no control over the rate of your heart.


11.  Go to Image #3 (The Four Lobes; be sure to wait for the eyes to stop moving, and for the buttons to appear.

List and describe the many Connections listed for the Frontal Lobes.  Be as thorough as possible.
