I have never done any experiments on human brains, some people do tests on human brains donated to science from people who have died. Other people can do experiments on pieces of human brain tissue from when somebody has an operation to remove some parts of the brain.

I just test the brains of living mice. I also use brain cells from rats, but they are taken from rat embryos and put on to a glass dish. We use these two animals as models of human brains because they have similar structure and organisation to our brains. The basic function of their brain cells is the same also, which is important for my research.
