There is another thing called the functional MRI or the FMRI which is mainly done to measure the cognitive activity by monitoring certain parts present in the brain. The blood flow also increases a lot in those areas where the neurons are active. Functional MRI helps researchers learn about the function of a normal, diseased, or an injured brain.
