Traditional fMRI imaging measures changes to blood flow in the brain, as a proxy for neural activity. When neurons receive signals from other neurons, it triggers an influx of calcium, which causes a diffusible gas called nitric oxide to be released. Nitric oxide acts in part as a vasodilator that increases blood flow to the area.This is actually the main objective behind doing a fMRI scan in the first place. While high-resolution MRI scans are performed to get static anatomical insights, fMRI scans aim at getting behind ...How does the scan work? For your fMRI scan, you will do tasks while MRI pictures are taken. Activity will increase in the area of your brain that is in charge of the task you are doing. This extra brain activity includes: • Blood vessels getting larger • Chemical changes occurring • Extra oxygen being delivered to that part of the brainA standard fMRI experiment generates many thousands of measures in one scan. This is a major advantage of fMRI (mass simultaneous recording), but raises a number of statistical challenges.That system was capable of reconstructing visual experiences from human brain activity, thanks again to fMRI brain scans taken while a subject looked at a visual cue.
