_____ detects blood flow to brain regions,indicating heightened neural activity.

Question

Quizplus · Accepted Answer

Functional magnetic resonance imaging (fMRI) is the imaging technique that detects changes in blood flow to brain regions, indicating neural activity. This is done by measuring changes in oxygen levels in the blood, which are correlated with neural activity. PET also measures blood flow, but it requires injection of a radioactive tracer, making it a less common and more invasive technique. CAT is used to create 3D images of the brain, but it does not provide information on neural activity. EEG measures electrical activity in the brain, but it does not provide spatial information on where the activity is occurring.
