While (provide) mild electronic stimulation to different areas of the motor cortex in fully conscious patients, researchers observe their bodily responses. 8. Functional magnetic resonance imaging (fMRI) measures blood flow in the brain during different activities, (provide) information about the activity of neurons and thus the functions of brain regions. 9.
