PET scan (Positron Emission Tomography) is the approach that researchers use to document changes in the brain's metabolic activity during problem-solving. A PET scan measures blood flow and oxygen and glucose metabolism in the brain, providing information on which regions of the brain are active during a cognitive task. EEG recording, MRI, and transcranial magnetic stimulation can also be used to study brain activity but are not as effective in measuring metabolic changes during problem-solving.
