• CAT scan

What does EEG measure in the brain?

• Blood flow

• Oxygen levels

• Magnetic fields

• Electrical activity

Which technique records magnetic fields produced by brain electrical currents?

• MRI

• CAT scan

What is the main advantage of FMRI over other imaging techniques?

• It is less expensive

• It combines structural and functional imaging

• It requires no special equipment

• It uses X-rays

How does FMRI determine which brain areas are active?

• By measuring glucose levels
