Name and explain 3 ways the brain can be studied.
Callosomtomy- split the brain in half via corpus callosum
EEG- measuring electricity along the surface of the scalp
FMRI- looks at oxygen use in the brain, shows structure and function
Hemispherectomy- removing half of the brain and looking at deficits
Lesion study- looking at deficits that result due to the destruction of brain tissue
MRI- uses a giant magnet to look at the structure of the brain
PET scan- utilizes radioactive sugar to look at where in the brain energy is being used
