Quizplus · Accepted Answer

When imaging techniques transcend structure and reveal brain activity, the methods used are functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). These techniques are tailored specifically to detect changes in blood flow, oxygenation and glucose metabolism in brain regions, and thus can provide information about neural activity in response to stimuli or tasks.
