Solution
The functional magnetic resonance imaging (fMRI) scan works on the knowledge that more oxygen is required for active brain neurons. When a particular area of the brain is in use, it requires more oxygen. To meet this demand, blood flow to that area of the brain increases. The fMRI scan detects these changes in blood flow and oxygenation, and this information is used to create a detailed image of the brain.
