Subject: In What types of conditions does the brain work best?

Hello, I'm an 8th grader at Silverado. We have a science fair coming up, and we 
have 3 broad topics to choose from: Physics, Chemisty, and Astronomy. I wanted 
to do my project on the brain. I was thinking about testing different people in 
different conditions such as: making them spin in a circle 5 times and make 
them try to remember things; making them hang upside down before attempting to 
remember things; and just making them sit there and they try to remember 
things. I'm having a little trouble finding information about how chemical 
activity in the brain is changed when a person is suspended upside down or has 
spun around a number of times. How are our brains affected? Thanks!
