Compare and contrast the methods used to assess brain activity
What will be an ideal response?
Answer: Doctors use the electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI) to assess brain activity. The EEG only measures activity in the cerebral cortex, but the fMRI measures in both the cerebral cortex and other areas of the brain. The EEG measures brain activity by detecting electrical activity, but fMRIs detect changes in blood flow and oxygen using a magnetic field. fMRIs are more difficult to use than the EEGs with toddlers and young children because with fMRIs they have to lie still in a machine for a long period of time.
