In fMRI studies, BOLD stands for blood-oxygen-level-dependent. A BOLD signal is a brain imaging signal that is increased or decreased by the level of oxygen in the blood within any given part of ... The system directs the pulse toward the area of the body we want to examine. When the pulse is applied, the unmatched protons absorb the energy and spin again in a different direction. This is the "resonance" part of MRI. The RF pulse forces them to spin at a particular frequency, in a particular direction.fMRI is based on the same technology as magnetic resonance imaging ( MRI) -- a noninvasive test that uses a strong magnetic field and radio waves to create detailed images of the body. But instead of creating images of organs and tissues like MRI, fMRI looks at blood flow in the brain to detect areas of activity.…

Since spatial frequency ( k) is [# cycles/distance], we can writ What fMRI actually represents. We’ve represented fMRI as a snapshot of MR signal over multiple timepoints. This is a useful way of understanding the organization of fMRI, however it isn’t typically how we think about the data when we analyze fMRI data. fMRI is typically thought of as time-series data.
