Imaging technology defines locations in the brain where neurons are especially active using safe radioactive isotopes to measure the metabolism of brain cells.

PET(Positron Emission Tomography)

Explanation:

Positron Emission Tomography is an imaging technology that scans the body to check for diseases. It uses procedures of nuclear medicine and certain biochemical analysis. It can identify locations in the brain where neurons are especially active using safe radioactive isotopes (such as carbon 11 and Nitrogen 13) to measure the metabolism of the brain cells.

Other functions of the PET are;

i. measurement of the flow of blood to and from the heart.

ii. the rate at which a body consumes or uses sugar.
