An fMRI scan uses the same MRI machine, but is special because it tracks blood flow in different parts of your brain. Your brain cells use more oxygen when they’re working. That means following the blood flow shows the areas of your brain that are working hardest. See moreFunctional MRI (fMRI) is a non-invasive imaging technique that measures brain activity by detecting changes in blood flow. It is used to examine the functional and structural aspects of the brain. fMRI measures the oxygen level in different areas of the brain, which helps researchers understand which regions are active during specific tasks or stimuli.

These detailed, high-quality images in two or ...Jan 10, 2018 · Using a "decoder," the researchers created representations of the brain's responses to the images, but in the DNN. From then on, they no longer needed the actual fMRI measurements, just the DNN translations. In guessing what someone was viewing, the translation acts as a template, and the fMRI data are set aside. Jun 9, 2023 · Next, the MRI machine applies a radio frequency (RF) pulse that is specific only to hydrogen. 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. What fMRI actually represents. We’ve represented fMRI as a snapshot of MR signal over multiple timepoints.
