Damon is injected with a radioactive substance and then lies on an apparatus with a scanner that emits fine streams of x-rays, which detect increased blood flow and oxygen metabolism in areas of the brain as damon processes particular stimuli. damon's brain functioning is being measured using

The answer is Position emission tomography (PET). The nuclear imaging procedure in medicine is able to detect even molecular activities in a cell. They are therefore effective in detecting cancers, cardiovascular diseases, neurological disorders, and etcetera. The radionuclides are modeled such that they accumulate in the targeted organ. They measure sugar (glucose) metabolism, blood flow, and oxygen utilization.
