Final answer:
fMRI is a technique that uses variations in magnetic properties to plot a detailed image of the brain. It operates on the principles of MRI and tracks changes in brain activity over time by monitoring blood flow and oxygen levels. OPTION A is answer
Step-by-step explanation:
fMRI is the technique that uses variations in magnetic properties to plot a detailed image of the brain. It operates on the principles of magnetic resonance imaging (MRI) but shows changes in brain activity over time by tracking blood flow and oxygen levels.
By interpreting the signals emitted by hydrogen atoms in the body's cells, fMRI provides more detailed images of the brain's structure and allows for the comparison of healthy and psychologically disordered brains OPTION A is answer
